4L 5s (3/1-equivalent): Difference between revisions

Bohlen-Pierce theory possesses a well-established [[nonoctave]] notation system for [[EDT]]s and no-twos music, which is based on this MOS scale as generated by approximately [[7/3]], relating it to [[Bohlen-Pierce-Stearns|BPS]] temperament, where two 7/3 generators are equated to 27/5. The preferred generator for any edt is its patent val approximation of 7/3.

This notation uses 9 nominals: for compatibility with [[diamond-MOS notation]], the current recommendation is to use the notes J K L M N O P Q R J as presented in the J Cassiopeian (symmetric, sLsLsLsLs) mode, and represented by a circle of generators going as follows: ...Q# - O# - M# - K# - R - P - N - L - J - Q - O - M - K - Rb - Pb - Nb - Lb... However, an alternative convention (as used on Wikipedia <ref>[https://en.wikipedia.org/wiki/Bohlen%E2%80%93Pierce_scale#Intervals_and_scale_diagrams]</ref> and certain articles of this wiki) labels them C D E F G H J A B C in the C Andromedan (LssLsLsLs) mode, which rotates to the E Cassiopeian mode.

An extension of [[ups and downs notation]], in the obvious way, can be found at [[Lambda ups and downs notation]].
