Function spellScale

spellScale(tonic: NoteLike, key: KeyLike): NoteData[]
Spell every pitch class of a scale, in ascending scale-degree order.

Correct for heptatonic scales (each degree gets the next letter). A gapped scale gives each of its tones a letter of its own wherever its pitch set allows one — C miyako-bushi spells C Db F G Ab — and is spelled tone by tone, on the accidental side the scale leans towards, where it does not: the blues scale has to name one letter twice however it is read.
Parameters
- tonic: NoteLike
  The spelled tonic, as a note name, a MIDI number, note data, or a Note.
- key: KeyLike
  The key/scale, as a key name, a key/scale, or a Key — the same forms its sibling spellers take.
Returns NoteData[]
Spelled notes, one per scale degree.
Throws
If key names no key, or if tonic does not sound the key's root pitch class.
Example
```
import { spellScale, noteNames, parseNote, majorKey } from '@libraz/libcantus';
noteNames(spellScale(parseNote('C'), majorKey(0)));
// ['C', 'D', 'E', 'F', 'G', 'A', 'B']
```
