Tutorials or cookbooks ?

Hello,

I am completely lost, I find some examples but I cannot get how I am supposed to use the library.

I would like to pick a root note (say 'G') and then a scale/mode, say ('aeolian'), and finally retrieve all notes in 'G aeolian' and get the list of all chords compatibles with this scale.

Are there guides to explain how to do that ?

Thank you.

Hi,

You're right. The documentation is not clear nor correct (I'll fix it soon).

Anyway, you'll need to use the @tonaljs/scale module. The documentation lives in the repository: https://github.com/tonaljs/tonal/tree/master/packages/scale

To obtain the scale properties, use the scale function:

import { scale } from "@tonaljs/scale"
scale("G aeolian").notes // => ["G", "A", "Bb", ... ]

To obtain the chords, use the scaleChords function from the same package:

import { scaleChords } from "@tonaljs/scale"
scaleChords("aeolian")

Hope it helps!

Hi,

Great! Don't hesitate to ask if you have more problems. I'll reopen the issue and close it when I fix the documentation.

EDIT: Suggestions on how to improve the module or the documentation are welcomed
