-- <ic>scale(scale: string, mask: number)</ic>: extrapolate a custom-masked scale from each list elements. [0].scale("major", 3) returns [0,2,4]. You can use western scale names like (Major, Minor, Minor pentatonic ...) or [zeitler](https://ianring.com/musictheory/scales/traditions/zeitler) scale names.
