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) #=> 10 (10th)
MusicUtils.semitones(:do, :mi, 1) #=> 16 (semi-tones)
MusicUtils.quality(:do, :mi, 1) #=> M (major)
Short Notation:
MusicUtils.short(:do, :mi) #=> M3
MusicUtils.short(:do, :mi, 1) #=> M10
Highest note of interval:
MusicUtils.high_note(:do, :P5) #=> :sol
MusicUtils.high_note(:fas, :m3) #=> :la
Scales
Create scales:
MusicUtils.scale(:fa, MusicUtils::MAJ_SCALE) #=> [:fa, :sol, :la, :sib, :do, :re, :mi]
Installation
gem install music-utils
Usage
The MusicUtils module has constants to refer to common items like notes and scales.
require 'music-utils'
MusicUtils.short(MusicUtils::SOL, MusicUtils::DOF)
MusicUtils.scale(MusicUtils::SOL, MusicUtils::MAJ_SCALE)
Testing
To run the tests:
$ bin/rake
or:
$ ruby bin/rake
