Harmonic bank + melodic review V0.8
Your live Rhythm Studio is untouched. This is an independent prototype, without logins or database connections. Version 3.7.9 remains the recovery version. This stage tests a single concert-pitch treble-clef melody with 4- or 8-bar tonal harmony.

Earlier Composition Lab V0.3 comparison
Both scores share the same key, available notes, note durations and seed. The selected style changes harmony and melodic writing. Jazz swing alters the playback timing of written quavers; both scores are notated evenly. Versions use different quality scoring rubrics, so numerical points are not directly comparable. Chord symbols and treble-clef notation are provided for listening and evaluation. Automatic quality scores are diagnostics, not proof of artistic quality.
How the reference framework informs this version
The uploaded Trinity flute, oboe, clarinet and saxophone scores informed the phrase and difficulty criteria. Tonal mode is preserved from V0.8. Genre experiments have their own original templates: jazz guide tones and seventh chords, funk groove-based harmony, pop chord loops and hooks. V0.7-style review then makes only cautious individual note corrections. It preserves good passing and neighbour notes and keeps the closing bar intact. The templates use established harmony and voice-leading principles, not copied melodies. Some combinations of restricted available notes require tonic substitutions. The scores are single-line examples, so chord functions and inversions are our compositional design rules, not extracted harmonies.
