how it works
Four layers, in any order you like.
Every section you analyze gets the same treatment — objective detail, formal role, what you felt, and what the composer is doing.
① Objective
Key, chords, tempo.
Enter the progression in Hooktheory-style roman numerals. Mark tempo changes. Pick instruments from a multi-select of what's actually playing.
Dm · 4/4 · 72 BPM i ♭VII IV i | i ♭VII V7 i
② Formal
Section role.
Is this an A-verse? A-prime? Bridge? Climax? How does it transition to the next — a sudden drop, a gradual swell, a subito piano?
A · verseA′bridge
③ Subjective
What you felt.
Tag the GEMS emotions. Drop a pin in the valence × arousal canvas. Stuck on the word? Let AI suggest precise vocabulary — bittersweet, hiraeth, saudade.

④ Compositional
The composer's move.
Name the technique — pedal point, modal mixture, orchestral swell, subito piano, braam. The library is extensible — add your own tags as you learn.

the palette
Nine feelings, one color each.
We use the GEMS framework — nine musical emotions, each with a signature color that threads through every section, tag, and pattern in the app.
