Method of determining mode RRS feed

  • Question

  • The method described in the MySong papers for separating lead sheets into major and minor is pretty complicated. Is there any reason why something like the Krumhansl-Schmuckler algorithm wasn't used instead?

  • I'm not familiar with Krumhansl-Schmuckler, but I just took a quick look... it looks like it's intended to operated on polyphonic sheet music; we didn't have that (just melodies and chords).  We could have synthesized arrangements for the chords, but overall our approach was quick to implement, only needed to run once, and - to our subjective evaluation - "just worked", so we didn't spend a lot of time revisiting.  It was basically possible to verify every case manually, so we're pretty sure this was not a high-risk step.

    Hope that helps!
