I practice Tai Chi Chuan every night & always have traditional Chinese or Japanese music playing in the background..If your system has any tendency towards brightness,stridency or shrillness you will absolutely hear it...
Guzheng rocks
Cleaning out my brother's estate and I came across a Guzheng. This led me to youtube to see how they sound. First video I landed on kind of opened my horizon's a bit. Never previously paid any attention to such music, and even though it's a traditional instrument, this song kind of Rocks!
