Howdy Daniel,
Nice work! I played each theme separately, and they are a bit short by themselves - themes, as you pointed out. However, I had them both open in the 1.9.2 beta, so that I could easily access the tabs, and I had some fun
I started Theme 1 playing, then clicked the tab for Theme 2 so that the score for Theme 2 was on the screen while Theme 1 was playing. As soon as Theme 1 was done, I used "P + click" at the first measure to start Theme 2 playing, so that it directly followed. Then, as it was playing, I clicked the tab for Theme 1 again, and as soon as the last chord played in Theme 2, I did "P + click" in the first measure to set Theme 1 playing again. I didn't change the key of either piece, and it sounded really nice to me played in this sequence in the original keys.
So the order that I played them in (no editing the files) was:
Theme 1 complete
Theme 2 complete
Theme 1 complete
Good stuff! Keep it up!
ttfn,
Sherry
