Scale
A scale is a set of musical notes ordered by pitch. Scribbletune uses tonal as a dev dependency to create a dumbed down version of it’s scales in another node module called harmonics and uses that as a dependency of Scribbletune (this is done so as to have a very small footprint in Scribbletune for the music theory).
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
