Function voiceProgression

voiceProgression(chords: ChordData[], opts?: VoicingOptions): number[][]
Voice a chord progression with smooth voice leading. The first chord is voiced with voiceChord; each subsequent chord picks, from a bounded deterministic candidate set, the voicing minimizing the voice-leading cost from the previous voicing plus a large penalty per counterpoint violation (parallel perfects/octaves, voice crossing, voice overlap, and over-wide upper-voice spacing).
Parameters
- chords: ChordData[]
  The chords to voice in order.
- Optionalopts: VoicingOptions
  Voicing options; defaults to four voices in SATB_RANGES.
Returns number[][]
One voicing per chord, each ascending with one MIDI pitch per voice.
Throws
If any chord admits no voicing within the given ranges.
Example
```
import { parseChordSymbol, voiceProgression } from '@libraz/libcantus';
const chords = ['C', 'Am', 'F', 'G'].map((s) => parseChordSymbol(s));
voiceProgression(chords); // one four-voice voicing per chord, smoothly led
```
