Would harmonic product spectrum would work here? In my experience, it works very well for detecting the note frequency of guitar, piano etc.

It may work with shorter windows for music that is rhythmically complex (more subdivisions would be analogous to more harmonics in the typical pitch detection application) but would certainly fall apart at lower tempos.
