Listen closer.
Write down what you felt.
Find your voice.
For hobbyist composers who study the music that moves them. Paste a YouTube track, cut it into sections down to the bar, name the feeling, note the harmony and the orchestration — and see which techniques go with which feelings across your library.
Cut it into sections. Annotate in three tiers.
Every section gets the same treatment — what you felt, what the harmony does, and how it's orchestrated. Fill in the tiers in any order.
Paste a track, mark the sections.
Paste a YouTube link. Set the BPM and meter, and the timeline snaps to bars — drag to create sections, drag boundaries to adjust, add timestamped notes as you listen.
Verse · bars 9–24
What you felt.
Tag the moods you hear in the section, then pin the precise words — from suggestions for each mood, or your own.
Chords and function.
Pick chords from the key's palette or paste a whole progression — Roman numerals are derived from the track's key. Mark phrase breaks.
i ♭VII IV i | i ♭VII V7 i
The composer's move.
Add the instrument layers that are playing and tag each with techniques — pedal point, ostinato, pizzicato, swell — or your own.
See the patterns. Share the analysis.
Techniques × feelings.
See your most-used techniques, how your moods are distributed, and a matrix of which techniques go with which feelings — with the sections behind every cell.
Read-only, your choice.
Keep an analysis private, share it by link (unlisted), or list it publicly on Explore. Only you can ever edit it.
Work on it with Claude.
Connect Claude through MCP from Settings. It can read your library and help annotate sections — moods, harmony, orchestration, notes.
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.
The patterns are already there.
We just give them somewhere to surface.
Start with one track you can't stop listening to. The rest follows.
