I was still in a prog rock mood after doing the Supper's Ready/Close to the Edge medley last week. So here's an early King Crimson song played on tiple.
When I looked up the chords of this song on Ultimate-Guitar.com a couple of years ago, it included an H7 chord. This perplexed me for a few days, until a friend Googled it and found out that in Germany a B7 chord is sometimes called H7. Internet lore claims that there was concern that the flat symbol looked too much like a B, so to avoid confusion between B and Bb the B was called an H. This makes no sense to me. But the Ultimate-Guitar chords were posted by someone from Germany, and I've seen H7 chords in a couple other postings since then.
