I recommend checking out my first "Methods & Mechanics" DVD as not only does the DVD lead off with "Tears of Joy" but I talk later about navigating the time signature (which is actually 13/8). I also speak a bit about Jerry Goodman who composed and performed it. (If you don't know who Jerry Goodman is.....Google him!)
Both DVDs are available from my web store and ships world wide right away....straight to your mail box! I hope you pick them up. On the MM2 DVD, there is another Jerry Goodman composition called "Going on 17," which has sections in 15/8 and 17/8.
