What’s a note?
A note is a frequency or pitch. If you’re by yourself, sing and hold the pitch steady. For our
purposes, that’s a note. And no matter what random pitch you just sang, we can call that
note by a letter name A, B, C, D, E, F, or G. The letter names cycle, meaning the note that
follows “G” is “A.” There is no “H.” Notes also have duration. And notes are perhaps
distinguishable from “pitch” and “tone” by whether they’re heard, performed, or written
down (notes and notations are written things), but we’re not concerned about any of that in
this lesson. Next…
What’s a scale?
scale because it’s hopping all around; it’s not directional. Scales don’t need to contain
exactly seven notes. They just often do. Next…
What is an interval?
An interval is the distance between any two letter-named notes. We can count it on our
fingers. For example, let’s take A and E. The notes A and E have an interval of five. We
count the first note of an interval as “one.” There is no zero. It’s an inclusive counting
thing. So, on our fingers, A is one, B is two, and E will be five. So the A to E interval is five.
If we play two notes together, we get “harmony” (the sound of more than one note at a
time) and we would call this particular harmony a “fifth.” A to E is a “fifth.” Note however
that A to E is not the same interval as E to A. Direction matters! On your fingers, if E were
“one,” then F is two, G is three, and A will be four. So the interval A to E is five or “a fifth,”
but the inverse, E to A, is four; “a fourth.”
A “half step” is the distance between two adjacent notes, and a “whole step” is two half
steps. It’s a bit like half-teaspoons and teaspoons. A “step,” whether it’s ‘half’ or ‘whole,’
is the distance from one note in a scale to the next or to the former. But “half step” is the
far more useful term because it lets us describe the precise distance between two notes,
as in, “exactly how many piano keys away from “C” is “F?“
What are ‘sharps’ and ‘flats?’ Sounds important, but I might’ve skipped this altogether if
we didn’t have five whole minutes left to kill.
Picturing that piano? The sharps and flats are the black keys, and you probably knew
that. This being a theory lesson though, let’s be at least minimally theoretical about it…
