Comment on Capo: My new Mac app for helping musicians learn their music

Comments

This is great.

How difficult would it be to detect the notes that are being played by the bass? This would be useful for someone who is new to playing by ear and soloing.

For example, you pickup that the bass progression is G A D C--that makes figuring out the correct chords (and notes for soloing) even easier.

It's not difficult to detect all the notes via FFT, slightly more difficult to detect only bass notes (harmonics come into play), and quite a bit more difficult to pull useful chords out.

That said, my first Mac app, FuzzMeasure, is an audio analysis tool---so I know my way around the FFT/etc. Read into this comment however you please. ;)
