music-utils

Utils to clasify music intervals, create scales and more.

Examples

Intervals

Simples:

MusicUtils.number(:do, :mi)                   #=> 3 (3th)
MusicUtils.semitones(:do, :mi)                #=> 4 (semi-tones)
MusicUtils.quality(:do, :mi)                  #=> M (major)

Compounds:

MusicUtils.number(:do, :mi, 1)                #=> 3 (3th)
MusicUtils.semitones(:do, :mi, 1)             #=> 16 (semi-tones)
MusicUtils.quality(:do, :mi, 1)               #=> M (major)

Short Notation:

MusicUtils.short(:do, :mi)                    #=> M2
MusicUtils.short(:do, :mi, 1)                 #=> M9

Scales

Create scales:

MusicUtils.scale(:fa, MusicUtils::MAJ_SCALE)  #=> [:fa, :sol, :la, :sib, :do, :re, :mi]
