Array

• In twelve-tone and serial composition, the presentation of simultaneous twelve-tone sets such that the sums of their horizontal segments form a succession of twelve-tone aggregates
• Array mbira, a musical instrument
• Spiral array model, a music pitch space

A telescope array, also called astronomical interferometer.

• Various kinds of multiple biological arrays called microarrays
• Visual feature array, a model for the visual cortex

Generally, a collection of same type data items that can be selected by indices computed at run-time, including:

• Array (data structure), an arrangement of items at equally spaced addresses in computer memory
• Array (data type), used in a programming language to specify a variable that can be indexed
• Associative array, an abstract data structure model composed of key-value pairs, often implemented as a hash table or search tree

or various kinds of the above, such as:

• Bit array or bit vector
• Dynamic array, allocated at run time
