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
Major scale semitone (i.e. whole, whole, half). The major scale is maximally even. \override Score.TimeSignature #'stencil = ##f \relative c' { </score> The scale degrees are: \override Score.TimeSignature #'stencil = ##f </score> The triads built on each scale degree follow a distinct pattern. The roman numeral analysis is shown in parentheses. If a piece of music (or part of a piece of music) is in a major key, then the notes "in" the corresponding major scale are considered "diatonic" notes, while the notes "outside" the major scale are considered "chromatic" notes. Moreover, the key signature of the piece of music (or section)
