Finally I am making a humble re-entry on the practice scene with San'ya (Mountain Valley). I feel like this piece will keep me occupied for about 20 years which is a distinct part of its attraction. Right now I am wondering about the San'ya Mountain Valley vs. Three Valleys because the music distinguishes between using the Kanji (pictured) and 三谷 while many recordings do not seem to share this demarcation. The track on a Yokoyama Katsuya recording bearing the title San'ya Dokoyku is the 11-12 minute piece that is usually known as 山谷 Mountain Valley. Yet both this CD, Ishikawa Toshimitsu's recording (In Dead Ernest II) and the International Shakuhachi Society komuso web site in describing this piece, use the Kanji, 三谷 (i.e. different from the music notation written by Furuya Sensei in transcribing Yokoyama Sensei). Furthermore, the page on ISS mixes recordings of both pieces, so it is hard to know which one the programme notes refer to really, e.g. the Ramos and Riley recording on that page are 3 Valleys while the Ishikawa recording is Mountain Valley. Then, of course, within each lineage there are different interpretations and still more versions! Kakizakai Sensei's Volume 2 Koten Honkyoku CD has now arrived and it uses 山谷 the same as the notation.
Watazumi Do's Hocchiku 法竹 CD programme notes for San'ya Mountain Valley state:
The piece Sanya expresses a state of contemplation, as symbolized by the serene flowing of a stream hidden deeply in the mountains. Contemplation is a part of Watazumi-Do's Way of Nature, and is centered around the secret breathing techniques whose purpose it is to train the breath and attain the unification of mind and body. Sanya began in Oshu, and, through sound, expresses the state of contemplation.
