Structs

ScaleRun

A run found: the notes in it, by their place among the stream’s own elements, and the way it goes, where it has gone one.

ScaleRunOptions

music21’s keyword arguments to findConsecutiveScale.

Enums

PitchAttribute

What two pitches must share to count as the same: music21’s comparisonAttribute.

RunDirection

Which way a run goes through the scale.

Functions

find_consecutive_scale

Every run of notes in a stream going one way through a scale, a degree at a time, that reaches at least as many different degrees as asked: music21’s findConsecutiveScale.
