The Associated Board of the Royal Schools of Music (ABRSM) in the United Kingdom
has commissioned and published the Spectrum series, which comprises several
collections for various instruments, with CD recordings. The collection for cello was
published in 2004 and features 16 pieces by living British composers which are ranked
in order of difficulty. A valuable collection for the young or amateur player, this
introduces several extended techniques and develops the ear to a non-tonal musical
language. The ABRSM also lists in its syllabus works from Fingerprints, Unbeaten
Tracks and the second of three volumes of the Collection Panorama – Violoncelle. The
Fingerprints collection brings together 14 pieces by living composers, though these use
more ‘popular’ compositional styles. Unbeaten Tracks features 8 pieces, ranked in
order of difficulty, though only the concluding work written by Steven Isserlis
incorporates non-traditional techniques (friction noise of the left hand sliding on the
strings, tapping the cello, overpressure, Bartók pizzicato, harmonics glissandi, and sub-
ponticello). The French Collection Panorama brings together 15 oeuvres
contemporaines in three volumes.
Excerpts from James MacMillan’s Northern Skies, seven miniatures written for
children, and Aaron Minsky’s 10 American Cello Etudes are also listed in the ABRSM
syllabus. A conspicuous lack of 20th-century masters are present though, extending
only in the higher grades to the early 20th century with Bartók, Janáček, Ravel, Bloch
and Prokofiev – many of the 20th-century works programmed in this syllabus are of
different cultural traditions: fiddle music, Hungarian folksongs, bluegrass, TV/movie
theme tunes, traditional Congolese, American jazz, and Latin.
The Royal Conservatory of Music of Canada and Trinity College London (TCL) also
present interesting cello syllabuses. The latter, as does the ABRSM, only introduces the
more celebrated names of the 20th century in the highest two grades. It is interesting to
note that the ABRSM syllabus does not require any études, while TCL does for the first
five grades, from their own publication Cello Scales, Arpeggios & Studies from 2007.
This syllabus also lists études from Minsky’s 10 American Cello Etudes and Dmitry
Kabalevsky Major-Minor Etudes for Violoncello, Op. 68. TCL offers the possibility for
students to perform their own composition at all levels and requires Grade 8

Etudes
When considering traditional performance practice, the correlation between didactic
materials and the performance of musical works of the same era seems to be
indisputable – for example, the study of J. L. Duport’s études develops notions and
techniques important to the performance of Beethoven’s works. While Methods
evolved in the 18th century in parallel to the encyclopaedia as we now know it, études
developed in the 19th century, in tandem with the rise of the virtuoso cellist. Dotzauer
and Grützmacher were among the first renowned performers to publish volumes of short
pieces intended for advanced students of the cello. These pieces intensively explored a
specific technical notion in a musical context. There followed dozens of étude books
throughout the 19th century, from the Russian, German, Belgian and French schools, the
style of which mirrored the musical taste of the day.
As the 20th century saw a tremendous diversification of styles and approaches, the
études written have come to represent their author’s particular idiom. This could be
illustrated in a separate investigation of more recent étude collections which could be
further evaluated, first individually then comparatively, in terms of their value to the
étude literature, a cellist’s development both musically and instrumentally, and the
understanding of the specific language of the composer in question.

PERFORMANCE TREATISES
Materials with very different formats – books, academic papers, and websites – have
been grouped into this section because of their similarities. Most of the works below
are intended for both composers and performers (though generally there is more
emphasis on orchestration, notation and context than on how to play something), which
dilutes the information and focus of the text. All of these texts provide performance
advice from only one source, the author(s), taking into account only one body-type and
one particular cello.25
Books
Several detailed instrumental treatises have been written. Though these works can be
very interesting to the performer, their format renders them impracticable to the cellist
wishing to acquire and refine new techniques. The works below are catalogues in
which pedagogy is not a priority.
The earliest publication of this type for a string instrument is Bertram Turetsky’s
Contemporary Contrabass (1974)26 and is unfortunately no longer in print.
25
This general absence in literature of comparisons between solutions by different players (with different
body types) is an observation which arose in interview, when the sheer difference in physical size
between N. Heyde and V. Welbanks became the obvious source of difference in their respective outcomes
for technical solutions.

listing examples specific to each one when appropriate. Both composers and
performers would find this text a useful point of departure for further experimentation
and reflection, however the information of each section is presented erratically; the
techniques Read selects are chosen from existing and mostly obscure compositions,
restricting the list to what has been done rather than what could be done. For the
extensive examples, there is a lack of actual illustrative notation, and many of those
provided are of poor printing quality, their purpose unclear. The book would be more
pleasant to read if such editorial considerations had been taken, and if translations of the
performance indications of his examples had been provided. Rather than fulfilling his
intent of codifying instrumental techniques as he suggests in his opening text, Read
provides an interesting, if superficial, introduction to the wide ranging transformation of
technique over sixty years.
The most recently published book of this type is co-authored by Irvine Arditti, first
violinist of the Arditti Quartet, and Robert HP Platz, a composer and conductor. The
Technique of Violin Playing (2013) is a lighter publication, presenting articles by either
Page 24
Part I: Where Are We Now?
author in both German and English text. It is pleasant to read and dotted with pertinent
anecdotes, but is, as with both previously discussed publications, primarily intended for
the composer. The techniques presented are those which are most commonly used by
Arditti himself. Notions of advanced interpretation, basic violin technique, and notation
are conflated, though each topic is clearly presented. The book provides a lexicon of
terms, a guide for writing double-stops, a chart of all possible harmonics for the violin,
and a very well-crafted DVD of Arditti playing the examples printed in the book.
All of these works use existing repertoire as a basis for the presentation of unconnected
techniques. These are all noteworthy resources for composers rather than performers.
Academic Papers
Several academic papers have been written concerning extended techniques for the
cello. Dylan Messina’s Where Will it End? A Guide to Extended Techniques for the
Violoncello written for his studies at the Oberlin College and Conservatory presents a
wider range of techniques than the two websites cited below, in a more structured
approach than Read’s compendium. Messina is both a cellist and composer but states in
his opening paragraph that the paper is intended as a resource for composers. As such,
the information is presented in clear, concise short articles with examples when
necessary and basic information about the means of production of a certain technique.

Page 25
Part I: Where Are We Now?
In comparison with the aforementioned works Ellen Fallowfield’s Cello Map (2010)
can be placed at the other end of the spectrum. It is very detailed, very thorough and
very systematic, but does not lend itself easily to assimilation by a student. In her work,
Fallowfield discusses as completely as possible the spectrum of sound production on the
cello to cover all existing and anticipated future techniques, though without any musical
context or priority towards classical technique so as to avoid any bias. While she makes
clear differentiations between theoretical models of sound production and practical
results, such a mix of knowledge requires the reader to ‘hunt’ for information. Indeed,
much of the information is given very factually, leaving the practical extrapolations to
the reader. Cellists would benefit from having access to her work in a re-structured
format which, as we will see below, she is endeavouring to do.

Websites
The following websites have been classified as performance treatises because of their
public-reaching efforts to present techniques in a pedagogical way. The quality of
presentation and the means of delivery vary widely.
Extended Techniques for Cello by Craig Hultgren29 takes the form of an academic
paper, and is divided into four sections: vibrato, harmonics, double-stops and pizzicato.
Hultgren develops each section starting from a very basic explanation, though his
approach is somewhat erratic and incomplete. His additional remarks on the use of
these techniques on the other bowed string instruments obscure the aim of his text. He
clearly addresses the composer who is not a string player or is unfamiliar with string
techniques, rather than addressing the amateur, student or professional cellist as do
Rolen and Fallowfield. Pragmatic advice is provided on what to do and not to do when
writing these techniques for string instrument along with some historically interesting
short introductory information on the technique in question. Even though he is a
performing cellist himself and a teacher, he offers no specific information about the
physical production of any of these techniques. The videos of the examples cited are
however very useful to both composer and cellist. His examples are mostly from music
written in the early 1990s, with very few taken from the more widely accepted
repertoire or recognized composers of the 20th century. This is surely a useful site for
composers wishing to gain better understanding of contemporary uses of these four
techniques, but the title is misleading as the text is extremely limited in the context of
the full range of extended techniques – only the section on pizzicato reaches into this
category, the other sections being limited to 20th-century uses of traditional techniques
in orchestration.

Part I: Where Are We Now?
While he intends to continue expanding the website, it already covers a wide range of
techniques in a systematic and pedagogically sensitive way. Rolen’s work resembles a
Method, very much based on those of the 18th- and 19th-century masters. To use his
words, it addresses the ‘proficient cellist’ who wants to learn 20th-century techniques.
Rolen also divides his work into four sections, the first two as left-hand techniques and
the last two as right-hand: harmonics, quarter-tones, ponticello & tasto, and pressure
techniques. Each section has multiple sub-headings, including a section with examples
from the repertoire, taken from an interesting mix of common practice and 20th- and
21st-century repertoire. Each page is accompanied by practice tips, printable exercises
(many of which are popular melodies), video demonstrations, examples, and diagrams.
The video demonstrations are essential in fully understanding the examples given, and
are generally very well played - as are Hultgren’s and Fallowfield’s. Though Rolen’s
website in its current form32 presents a somewhat narrow selection in terms of the full
range of extended techniques, the material presented would provide a solid basis for
acquiring confidence in the performance of modern music.
Fallowfield has also very recently rendered her thesis into a website. The main flaw in
Fallowfield’s Cello Map33 is design; it lacks the clarity and simplicity of Rolen’s. The
pages are very long, the text is in a small font, and the language is – though very
accessible – still very close to the language she uses in her thesis and not quite
accessible enough yet for an instruction manual. There is also much repetition in her
text. The many videos are a redeeming feature of the website, and show interesting
experiments in the acoustic phenomena she discusses.
Fallowfield best summarizes her own work, explaining that her text maps:
...“actions that a cellist can make” onto “sounds that a cello can produce”. In other
words, we have tried to reduce the cello and cellist to scales of actions and sounds,
and show how cellists can influence sound (loudness, overtone content, pitch…) by
their actions (bow speed, contact point, stopping position…). This standpoint is a
deliberate move away from providing performers and composers with catalogues
of special effects and extended techniques. Instead, we would like to provide

information about how the cello works that can serve the imagination of performers
and composers.34
Because of this tactic, the information provided on her website is also applicable to
standard technique, the relevance to modern music not always immediately obvious.
But this basic information is indeed essential in understanding how to break the limits
of traditional playing, to enter the realm of extended technique.
In contrast to Hultgren’s website, both Rolen and Fallowfield steer clear of discussing
any compositional use of the techniques they survey. While Rolen focuses entirely on
the nuts-and-bolts execution of the techniques, Fallowfield emphasises the acoustic
working of individual mechanisms of sound production, adding practical execution
remarks when appropriate.

SUMMARY
It remains that for all of the didactic literature written in the 20th and 21st centuries, no
material exists which can comprehensively and systematically guide a cellist in
acquiring the skills needed to adequately perform modern music. To accomplish this,
the required publication would need to be presented in a clear and appealing format.
The strongest aspects of the abovementioned publications would ideally be combined: a
wide range of the techniques most used in existing repertoire, presented in a logical
progression with a balanced mix of historical, theoretical and practical information.
Preparatory exercises would be followed by an opportunity to place a particular
technique into a musical context – acquiring practical knowledge of a given technique
can be achieved through executing it in isolation, but being able to apply a technique as
a component of artistry is dependant of its understanding in various contexts. Parts II
and III establish the foundations needed to accomplish these aims.
Page 30
Part II: Defining & Codifying Extended Techniques
The 20th century saw such an explosion of traditional technique that an order, a system
must be created on which to found a pedagogical approach. Every aspect of traditional
playing has been pushed to an extreme or disassembled, and entirely new ways of
producing sounds on the instrument have emerged. I will refer to this collectively as
‘extended technique’.
Extended techniques are intrinsically difficult to define; many date back to the earliest
days of cello playing, others ‘arrived as accoutrement to the romantic virtuosi’.36 It
was, however, with the virtuosity of 20th-century cellists such as Rostropovich and
Siegfried Palm that ‘the musical viability of extended techniques solidified; that they
could act as gestures of expression in and of themselves, rather than be relegated to
mere accessories of core technique’.37 Rohan de Saram expresses an interesting view
on the subject:
Learning to play an instrument is naturally not a linear process, but a rough time-line
could be drawn between the first cello lesson and the point at which a cellist can
comfortably play any common practice repertoire. The first few lines of the progression

This division is of course purely academic, many extended techniques can be used quite
early on in a cellist’s progression by a sensitive pedagogue, for example sul ponticello
can be introduced as soon as a pupil learns about bowing perpendicularly to the string;
this trains the pupil to associate physical movement with sound result, sul ponticello
being a particularly recognisable sound which changes immediately with the point of
contact. This could be the subject of a different study addressing the earlier stages of
learning.
There are many possibilities when considering the classification of such a vast body of
knowledge. Several authors, such as Read, P & A Strange, and Rolen, have grouped
their material according to left- or right-hand use. Fallowfield chose to order her
research independently of traditional playing, shaping her work according to acoustic
possibilities of sound production on the instrument. Katherine Jetter Tischhauser
chooses to define extended techniques as those for which ‘a composer creates a new
notation in order to convey to the performers of his work his intention regarding a
Page 32
Part II: Defining & Codifying Extended Techniques
different timbre, special sound, or effect’.39 To summarize, the works reviewed in Part I
classify techniques according to which part of the body is traditionally used, the
mechanics of the instrument, or notation.
When looking to integrate extended techniques into the performance of modern music, a
third category emerges, that of Musicianship. These seven sections are presented
separately in Part III, since ear training, rhythm, idiom41, and the use of technology are
skills transferrable to all musicians.
The rudimentary scheme outlined above Figure 1 mentions three aspects of learning the
cello: mechanics, geography, musicianship. While all 24 sections of this thesis involve
a combination of these three aspects, each technique tends towards one or the other.
Hence Part II covers predominantly physical techniques, dealing with the mechanics of
playing the cello and geography of the instrument, while Part III is dedicated to general
musicianship skills.
All sections in Part II, both large and small, are based on the action / mechanics of
performing a certain technique; the question of ‘how’ a technique is executed is the
guiding concept. The result may be seen as a catalogue, but the underlying principles
guide and shape it into a pedagogically sensitive framework: this is not a list of isolated
special effects but rather the most basic expression possible of available means of sound

production on the cello. The following techniques are presented as a linear projection
of traditional playing, so that the student may feel that this is not something entirely
new, but rather a continuation of skills that have already been acquired through years of
study. The numbering of each section will continue throughout Parts II and III, to
emphasise this sense of progression.
While every aspect of traditional playing can be transferred to the context of modern
music, the reverse statement is not true. But this clear demarcation of old and new is
what must be avoided. Another way of explaining the choice of content is that the
techniques included below are those which have the capacity of altering the sound
considerably in relation to common practice music and which necessitate added
proficiency on the instrument. For example, while vibrato is as much a consideration in
modern music as it is in traditional playing, a cellist with good vibrato control will have
the necessary technical knowledge to adapt its use to new musical contexts. Vibrato is
therefore not included, but extreme vibrato, which necessitates a different arm motion,
is included.
42
Often, the beginning of a technique will be linked to its first appearance in notation. In private
correspondence with V. Welbanks, Peter Sheppard-Skaerved explains that prior to the mid-1700s, ‘very
few special effects were notated - and this seems to be a legacy of an improvising culture. The early
violin virtuosi, Walther, Playford, Matteis, Biber, Ziani, etc., did not notate special techniques, but did
notate imitative ones [for example the 28th and final piece from Johann Walthero’s Hortulus Chelicus].
So I would suggest that what one would be looking for would be anything which asked for the evocation
of, say, aeolian harps, organs, etc.’
Page 34
Part II: Defining & Codifying Extended Techniques
While the relationship between performer and composer is an interesting one, the
latter’s role will be deliberately overlooked in this thesis. Notation is used throughout
this thesis in a purely illustrative way; in general, the most visually engaging notation –
rather than the most frequently employed – is used in examples, while the Notation
sections demonstrate what a performer might encounter in a score. Many other
publications have provided comprehensive lists of available notation and such a task lies
well outside the scope of this work. Much of the difficulty in systemizing extended
techniques lies in the fact that notation itself has not yet been standardized, despite
several valiant efforts to do so. Many techniques are as yet nameless and remain a
written description of either the action or the resulting sound by composers in their
prefaces. Where possible, all terms in use are included in headings, but much of the
terminology in this thesis has been created specifically for this text (this is indicated
when this it is the case).
The techniques below and their order of presentation are not biased in terms of use in
solo, chamber and orchestral repertoire; rarely used techniques are on equal terms with
those more frequently used. These are all, however, absent in traditional pedagogical
material. Each technique is presented in as isolated a manner as possible as a ‘digest’,
though in a musical context various techniques are often combined. As the combination
of any number of these techniques can become a technique in itself, section ‘17.
Independence of Hands’ (p. 177) is dedicated to a few examples of mixed techniques
which were separately surveyed in the previous sections. As students progress from one
section to another, they are encouraged to combine previous sections to explore the full
range of tonal possibilities on their instrument; for example, once the student has
progressed to the bowing techniques developed in sections 3 and 4, these should be
combined with harmonics, seen in section 1.
Many of these techniques are idiomatic and vary with the cellist’s body type and the
instrument itself, even producing widely varying results on each of the cello’s four
strings. The type of string43 used is the most significant factor. While a variety of
43
The material used for the winding and the core, the type of core (whether single or rope for the lower
strings), and the thickness of the string all affect the sound.
Page 35
Part II: Defining & Codifying Extended Techniques
players have been interviewed, and the different solutions they have offered described
below, the author would encourage both teachers and students to re-explore each of
these techniques on a particular instrument and to discover above all the scope of their
own sounds. While the solutions presented are based on information obtained by the
individuals’ own experiences, the author would like to emphasise that other solutions
have been or will be found by others.
While this thesis does not intend to be exhaustive, at the time of writing it is very nearly
so. As seen in Part I, many works examine basic extended techniques, and others are
in-depth presentations of a specific topic. This paper is unique as a comprehensive
overview of extended technique in its entirety.
In presenting the material below, the author has endeavoured to follow one basic
principle: the mechanisms of playing the cello in new music should remain as similar as
possible to traditional playing.

Part II: Defining & Codifying Extended Techniques 1. Harmonics
1. HARMONICS
We begin our exploration of extended techniques from a territory which most
performers feel is familiar, but in which only a rare few are comfortable. Harmonics are
part of a longstanding tradition in string playing and have been present in the earliest
Methods45 and indeed in the early stages of our development as cellists. Many
publications and exercises are dedicated to harmonics, and, to avoid lengthy duplication
of their content, students will be strongly advised to read Caroline Bosanquet’s The
Secret Life of Cello Strings: Harmonics for Cellists46 as a preparation to this section.
The study of harmonics will form the basis for many of the other sections in this thesis;
understanding harmonics and their role in sound can be likened to a mechanic
understanding the different components of an engine. Familiarity with the geography
and mechanics of harmonics on the instrument is essential in understanding how sound
is created and how timbre is modified with extended techniques, as well as how
dissonance and tuning systems function. Extended techniques specific to harmonics are
discussed later in this section (Applications, p. 53).
Some definitions are first in order as there is much misuse of vocabulary surrounding
harmonics. The term ‘harmonic partial’ is shortened interchangeably to either
‘harmonic’ or ‘partial’. This text will only use the word ‘harmonic’ for the sake of
clarity, to define ‘isolated harmonics’. The word ‘overtone’ will be used solely when
referring to harmonics as a component of sound, as in the context of overtone exclusion
or when describing timbre. An overtone is any component of a sound other than the
fundamental, which is higher than the fundamental. This can describe either harmonic
partials (whole-number multiples of the fundamental) or inharmonic partials (non-
45
While harmonics are mentioned in the Preface to Corrette’s Méthode (1741) as integral parts of the
sounds of an open string, the technique of isolating a harmonic is not discussed.
46
Bosanquet (1996).
Page 39
Part II: Defining & Codifying Extended Techniques 1. Harmonics
The portion of string between the nut and the 2nd harmonic, or mid-way point, is called
the lower half of the string. The portion between the 2nd harmonic and the bridge is
called the upper half of the string. Based on J. L. Duport’s introduction to harmonics48
and Bosanquet’s methodology, the upper half of the string will be taught first because
this is where the harmonics sound at pitch.
47
The 2nd harmonic partial =1st overtone, the 3rd harmonic partial = 2nd overtone, and so forth. This is a
common mistake because of the inherently confusing nature of having two numbering systems. An
additional element of confusion is added with the German terminology Oberpartialton which is shortened
to Oberton (which can be seen in the opening passage of Ligeti’s String Quartet No. 2, where he labels
certain harmonics). A cellist comfortable with the position and resultant pitch of harmonics can easily
overlook this enduring discrepancy in terminology.
