0100skala

0100Skala is a concept in music theory and algorithmic composition that uses binary notation to define scales within an octave. The name combines a binary string with the word skala (scale) used in several languages.

In this framework, a scale is represented by a binary string whose length matches the number of pitch classes considered; each position corresponds to a pitch class, with 1 indicating inclusion and 0 exclusion. In common practice Western tuning with 12 pitch classes, the mask is 12 bits long; shorter examples such as 0100 are used as illustrative motifs or templates when teaching the idea of bitwise scale selection.

The approach enables easy transposition, generation, and computational manipulation. It is commonly implemented in software tools for digital audio workstations, modular synthesizers, and algorithmic composition libraries, where bit masks can be shifted or combined to produce new scales.

Variants include longer masks, cyclic or windowed scales, and rhythmic or melodic applications where the binary sequence governs note onsets or scale membership across an excursion through the octave. The concept is primarily of interest to researchers and practitioners in experimental, microtonal, and computational music.
