Summary[edit]

Description
English: Slonimsky's Pyramid chord: [A,] A, G, F, D, B, F, C, F, A, C, D, E. The Pyramid chord contains all intervals (stacked, low to high, from 12 to 1) but not all pitch classes. The mother chord may created from the pyramid chord by transposing the underlined notes (0369) down two semitones.[1] "All chords composed of 11 different intervals add up to the interval of 66 semitones, which is the sum of the arithmetical progressions from 1 to 11. The interval of 66 semitones equals 5-1/2 octaves, and so forms a tritone between the lowest and highest tones in the Pyramid Chord."[2][3]

Licensing[edit]

This media depicts a chord outside of a specific musical context. Chords consist of an unordered collection of pitches outside of time (no "distinctiveness"), may be used in compositions by multiple composers ("common material"), and may not be readily apparent in compositions. As such, a chord is a musical concept or technique, which is considered too simple to be eligible for copyright protection, or which consists only of technique, with no original creative input.
