Korea has a very unusual array of sonic traditions and ways of thinking about sound. It has several systems for ceremonial court music. One is uniquely its own and could be a valuable resource for those who really seek to think outside of the sonic box.
The particular form which I ineptly remember involves metallic sounds and wood block sounds amid silences and a churning sense of surprise.
I had a Lyrichord cd of it but gave it away to Lola Danza as it is part of her heritage.
Now one hobby I have as an amateur ethnomusicologist is tracing phenotype patterns of instrument preference. Gongs are a big deal in the regions of Indonesia and the Phillipines moving up to Indochina where the Zither continuum begins.
In Vietnam the instrument is called a dan tranh. It becomes the guzheng in China, the koto in Japan and finally, the kayagum in Korea. More summer sounds, enjoy!.
