I've been working on chord-melody playing for the last couple months, and occasionally posting some of the tunes on our youtube channel, www.youtube.com/campusfive.com. One of the most common comments on those videos is a request for another chord melody lesson and/or a transcription.
I recorded and posted this video of "Sunday" yesterday, and I was able to crank out a rough transcription this afternoon. I wanted to get something up asap, since I tend to start, but then never finish, stuff like that. So, here's a tabbed-out transcription of the head of the tune.
Here's a link to a PDF. At some point, I'll try to sketch out the second, ad-lib chorus. Cheers.
