Harmonics

Tools and utilities for a generic representation of scales, chords, progressions etc. for use in music software, music related web & mobile apps, scribbletune, VCV Rack plugins and Max for Live devices. Uses tonal for western classical and custom generators for other forms of music.

Install

``bash
npm install harmonics
`

Interface

Use harmonics in your project

`javascript
const harmonics = require('harmonics');
`

Get an array of commonly used scales exported from Tonal

`javascript
harmonics.scales(); // ['ionian', 'dorian', 'lydian', '...']
`

Get the notes of a scale as an array

`javascript
harmonics.scale('C4 major'); // ['C4', 'D4', 'E4', 'F4', 'G4', 'A4', 'B4']
`

Get an array of all the available chords (with numeric chords such as 4, 5, 7 etc exposed as 4th, 5th, 7th)

`javascript
harmonics.chords(); // ['M', 'm', 'maj7', '4th']
`

Get the notes of a chord as an array (defaults to the 4th octave)

`javascript
harmonics.chord('C4 M'); // ['C4', 'E4', 'G4']
`

Get the notes of a chord as an array for a specific octave

`javascript
harmonics.chord('C5 M'); // ['C5', 'E5', 'G5']
`

Get the notes of an "inline" chord such as CM or Cmaj7 or Dbsus4_6 (here 6 is the octave). This is used in Scribbletune where you can define a bunch of notes and use chords in between, e.g 'C4 E4 Csus2 G4' (here Csus2 is "inlined" with C4, E4 and G4)

`javascript
harmonics.inlineChord('CM'); // ['C4', 'E4', 'G4']
harmonics.inlineChord('CM_5'); // ['C5', 'E5', 'G5']
