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
Insen scale Insen scale Insen (or In Sen) is a tuning scale adapted from shamisen music by Yatsuhashi Kengyō for tuning of the koto. It only differs from the hirajoshi scale by one note. In D mode it consists of: D-E-G-A-C so it has the same notes as the Phrygian chord (7sus♭9). Other chords compatible with insen scale include M7♯11 when the scale is played half steps lower (for example B in sen scale for CM7♯11 chord) and Cm6 and Cm when the scale is played one full step above (for example D insen with Cm6 or Cm chord).
