Has anyone used the app Capo–https://apps.apple.com/us/app/capo-learn-music-by-ear/id887497388– or something similar to help learn to play a song by ear on the shamisen? You can use songs you own and Capo guesses the beats, chords, and key of songs to help you break them down to their individual parts. It also allows you to slow down the tempo of a song without altering the pitch. If it offered chord diagrams for shamisen it would be perfect! If anybody has tips for using this app with a shamisen I’d love to hear them. Maybe if enough people buy the app and request it the developers would add shamisen to the offered chord diagrams.
