A bit obscure, but I (attempt) to badly play the Japanese Shakuhachi. It's an end-blown bamboo flute that attributes a great part of its history to being associated with Zen Buddhism (specifically Sui-Zen). It is touted as being one of the simplest (construction) non-percussive instrument in the world - i.e. a bamboo tube with five holes and an angled blowing edge. It is also reputed to be the most difficult/complex woodwind instruments in the world to play. And I play it rather poorly after some 20 years of lackadaisical attempts at practicing.
Actually, when I started, I played/practiced every day and had gotten almost pretty fairly kinda almost half decent - of course I had a teacher then. For the past fifteen years, I have been without a teacher and have lost almost all of the self-discipline needed to sit down and practice, so I have gotten quite pathetically ignorant of the ability to play anything but the first piece I learned. Also the music is all in Japanese notation (not that matters, I couldn't read western music notation any better).
It is a beautiful instrument and I have six of them in various sizes and styles (root-end ji-ari, root-end ji-nashi, non-root end ji-nashi, non-root end black bamboo ji-nashi, 1.8 shaku to 3.0 shaku).
Someday, I'll revisit them and start playing (my therapist has been telling me I should).
