Reference-informed engine Prototype 0.5
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.
1. Compose and compare
2. Examine the musical results
Earlier Composition Lab V0.3 comparison
Both results use precisely the same note palette and rhythmic sequence; they are two independent compositions, not identical melodies. 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. V0.5 specifically adds cadential voice-leading evaluation, soft control of repeated interval types, planned penultimate-bar rhythm where practical, and reduced pressure to repeat interval motifs. The scores are single-line examples, so chord functions and inversions are our compositional design rules, not extracted harmonies.
