Scale

A scale is a set of musical notes ordered by pitch. Scribbletune uses tonal as a dev dependency in harmonics to expose a dumb downed version of it’s scales (or modes).

The scale method takes a string input that denotes the key and the scale you want.

const scribble = require('scribbletune');

// Get the C major scale
let cMajor = scribble.scale('C4 major'); // [ 'C4', 'D4', 'E4' ... ]

// That's the same as
cMajor = scribble.scale('C4 ionian'); // [ 'C4', 'D4', 'E4', 'F4' ...]

// Create a clip that plays this C major scale
const clip = scribble.clip({
  notes: cMajor,
  pattern: 'xxxxxxx'
});

// Export this clip as a MIDI file
scribble.midi(clip, 'c-major.mid');

This will generate a MIDI file at the same location as you run this script. This is how it sounded when I imported the generated c-major.mid MIDI file into Garage Band

Scales are also exposed as modes.

let cMinor = scribble.mode('C4 aeolian'); // [ 'C4', 'D4', 'D#4', 'F4' ...]

You can list all the available scales by invoking scales or modes method.

const allScales = scribble.scales(); // returns an array of all the available scales from tonal
