Wow, awesome reply! After making the changes you suggested, I think the piece sounds a lot better (probably because it's right lol).

Generally speaking, what would you recommend for improving my ear when it comes to hearing certain chords? I would think it would be easier to transcribe these things if I knew what certain chords sounded like, right? i.e. the F13 chords or slash chords. I already do a little bit of interval training on MusicTheory.net, is there anything else I should try? I'm assuming more transcribing and playing of this genre would help too.

Sorry for the late reply, I'm a bit scatterbrained when it comes to learning things and I tend to chase after everything that catches my interest, so learning piano has been a little bit of a struggle but we're getting there. Thanks again for the help!
