Scale (music) identified by using a binary system of twelve zeros or ones to represent each of the twelve notes of a chromatic scale. It is assumed that the scale is tuned using 12-tone equal temperament (so that, for instance, C is the same as D), and that the tonic is in the leftmost position. For example, the binary number 101011010101, equivalent to the decimal number 2773, would represent any major scale (such as C–D–E–F–G–A–B). This system includes scales from 100000000000 (2048) to 111111111111 (4095), providing a total of 2048 possible species, but only 351 unique scales containing from 1 to 12
Chord-scale system the system. For example, Russell associated the C major chord with the lydian scale, while teachers including John Mehegan, David Baker, and Mark Levine teach the major scale as the best match for a C major chord. Miles Davis's "Lydian Chromatic Concept"-influenced first modal jazz album "Kind of Blue", is often given as an example of chord-scale relationships in practice. The chord-scale system provides familiarity with typical chord progressions, technical facility from practicing scales and chord arpeggios, and generally succeeds in reducing "clams", or notes heard as mistakes (through providing note-choice possibilities for the chords of progressions), and building "chops",
