================
The composition "Binary Digits" is loosely built on a binary structure. The work can be divided into three sections:

The 1st section has a "bit-length" of 1 (2^0). All the parts, like the clarinet and the piccolo/Eb-clarinet, are single.
The 2nd one has a "bit-length" of 2 (2^1). In terms of counts of eighth notes, is twice as long as the first section. Also, all parts are like a duet, in a free canonical form.
The 3rd section has a "bit-length" of 4 (2^2) and lasts twice as long as the second one and, therefore, four times as long as the first section. And as you can guess, this is kind of a quartet, again in a free canonical form.
In all sections, instruments like the flute, oboe, and marimba play a "binary counter". One hit stands for a "0", and two hits stand for a "1". There is one bit to count in the first segment, two bits in the second one, and four bits in the third.

And there’s one more thing: The structure of this work also partly relies on the prime numbers "11" and "101" (3 and 5 in a decimal system). The maximum value of a 4-bit number is 1111, equal to 15 in our common base-10 number system. "3" and "5" are the two prime factors of 15.

"A bit is the basic unit of information in computing and digital communications. A bit can have only one of two values, and may therefore be physically implemented with a two-state device. These values are most commonly represented as either a 0 or 1. The term bit is a portmanteau of binary digit. . . . The length of a binary number may be referred to as its bit-length."
