Honshirabe, or Honte no Shirabe, is one of the basic pieces of Honkyoku. While it is technically a beginner’s piece, it’s not simple. There are a lot of tiny details in the piece. And it can be played in many ways, with different schools having their own versions. (Check out Chiku Za playing the piece in the Zensabo style.)
Shawn Renzo Head has published a tutorial about the piece. Lasting just over 17 minutes, it goes into great detail. While it won’t help much if you’re a real beginner, if you’ve got some experience under your belt, you’ll find this to be very useful.
