Scale: Difference between revisions

Line 25:

Scales are generally treated with a greater focus on melody, while chords are generally treated with a greater focus on harmony. That said, the boundary between the two is fuzzy, and some musicians use the term ''scale-chord'' to refer to a set of pitches that is treated both as a scale and as a chord.

== Reentrant scales ==

A '''reentrant scale''' features at least one '''negative step''', going backwards relative to the general direction of the scale. Although a reentrant scale is not strictly ascending or descending, its ascending and descending forms are determined by its general direction.

This concept is mostly relevant when applying extreme tunings to abstract scales, causing some steps to have a negative size in order to preserve the abstract scale's usual structure. For example, if you try to generate a [[MOS scale]] with a [[generator]] whose size falls outside of the generator range of all possible MOS patterns with the same given number of notes, you should obtain a negative MOS scale. A 7-tone scale with a 295{{cent}} generator is just outside of the range for [[4L 3s]], and can be interpreted as a 4L 3s scale with 315{{cent}} large steps and -20{{cent}} (negative) small steps.
