i wanted to learn trumpet, and i really love chet baker.<br><br>so i asked codex to find transcriptions of his solos.<br><br>that turned into a much bigger project than i expected.<br><br>it searched musicians’ websites and academic jazz archives, found legitimate sheet music and midi files, verified which recordings actually contained trumpet solos, and converted everything into notation for b♭ trumpet.<br><br>one midi had more than 2,000 guitar notes. codex identified the actual trumpet part instead.<br><br>for solos that were only visible in publicly available videos, it reconstructed the notation and credited the original arrangers.<br><br>then i kept asking for things:<br><br>show me the valve fingerings.<br>let me change the key and tempo.<br>explain scales like i’m a beginner.<br>give me an actual learning path.<br>loop the hard parts.<br>add walking bass and backing tracks.<br>build me a 10-minute practice session.<br><br>now i have a personal chet baker practice app with ten playable pieces, guided lessons, phrase looping, and three different backing bands.
