Questions about Voice Leading Checker.
The practical details behind the request, access and result.
Can the Voice Leading Checker find parallel fifths in my music?
Yes, it specifically identifies parallel fifths and octaves between your chord voicings. It helps you catch these common harmonic errors instantly.
How does Voice Leading Checker help with choral arrangements?
It audits your SATB parts to ensure that voices stay in the correct order and that your transitions are smooth and technically correct.
What kind of musical analysis does Voice Leading Checker perform?
The capability performs an analysis of note conduction, voice hierarchy, and transition smoothness. It checks for leaps, crossings, and classical harmonic violations.
Can I use Voice Leading Checker to check my SATB voicings?
Yes, it is designed specifically for SATB (Bass, Tenor, Alto, Soprano) arrangements. It validates the movement of all four melodic ranges at once.
Will Voice Leading Checker suggest better ways to write my chords?
Yes, when it detects a violation, the capability provides suggested alternative voicings. This helps you correct errors while maintaining your intended harmony.
How does Voice Leading Checker score my music?
It provides a smoothness score based on the magnitude of note leaps and the number of harmonic violations found in a transition.
How can an agent detect parallel fifths?
Agents use the analyze_voice_conduction capability, providing initial and target voicings. The capability identifies when two voices move in the same direction while maintaining a perfect fifth interval.
What does `check_voice_hierarchy` do?
The check_voice_hierarchy capability ensures that the pitch values for Bass, Tenor, Alto, and Soprano are in correct ascending order, preventing voice crossing errors.
Can I get suggestions for better voicings?
Yes. When using analyze_voice_conduction, the capability returns a suggested_voicing object containing an alternative arrangement that resolves detected violations.
