Lamenting the Passing of Spring - was composed in the same tuning as the famous piece, 'Spring Sea', to evoke a feeling of deja vue. The piece expresses the joy of experiencing the season of awakening as well as the sadness of knowing that it is soon over.
	Shakuhachi - The Art of Yokoyama Katsuya	Shakuhachi : Yokoyama Katsuya
A duet for koto and shakuhachi composed by Yokoyama in 1981. The most well-known piece written for this combination is Miyagi Michio's composition "Haru no umi" ('Spring Sea') (1929). "Haru no umi" was originally written for flute, not shakuhachi. However, as the number of shakuhachi players who can play determined notes precisely and expressively has grown, the tune has become an important one for shakuhachi players as well. Yokoyama, being wall aware of the tune's existence, set the tuning of the koto to match "Haru no umi" and succeeded in creating a subtle ensemble of the two instruments proper to chamber music.
