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 versions share the same key, permitted pitches, rhythm and seed, but the harmonic bank may choose a different chord plan and therefore a different melody. 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 our phrase and difficulty criteria. V0.8 draws on transposable tonic, predominant, dominant, inversion and cadential templates and writes a fresh melody under the chosen harmony. 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 bank is guided by harmonic-function and voice-leading resources, 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.
