Hey,
I haven't been on the board in ages...but I recently just heard this song and I have to agree that it is awesome. Definitely one of Dan's best works.
brad is on the right track, but harmonically this song is a lot more advanced than just simple major and minor triads (Dan always manages to display his harmonic knowledge and sophistication in his tunes...unfortunately makes the transcription part a lot more difficult, especially if you are trying to find the exact voicings that he is using). From the first two listens, I can heard the basic harmonic outline of each section, but I'll have to sit down with a guitar to actually figure out the voicings and details. Unfortunately, I have a hefty composition assignment, not to mention a lengthy exam on modal counterpoint, to finish this week. But if you can be patient, I can get you a tab of this tune sometime this weekend if no one has tabbed it out yet.
Take care,
-Brent
