	New Spirits of Sangen	三弦 : 西潟昭子
Solo works for the shamisen are extremely rare in both the traditional and modern repertoires. That stems in part from the technical difficulties of performing very fast passages due to time required to move from kandokoro (a position on the finger board) to kandokoro, which are spread further apart than the violin. And because the shamisen's musical line traditionally follows the vocal line, traditional melodic phrasing is not suited to the solo repertoires in Western music terms. Given these difficulties, it is not easy to compose a solo work for the shamisen. I was finally able to produce this piece for Nishigata in 1980 after many frustrations and suspensions. As I intentionally tried to overcome the major weakness of the shamisen, or the lack of speed, this could be considered a rash work. In another sense, however, it could be considered the first step toward a new playing style for the shamisen. But given the high technical virtuosity it requires, Nishigata may be the only person capable of performing this work. The piece comprises passages of tranquil undulating movement and sharp, scraping rhythms. The title is derived from the light-hearted sense of skipping along while humming "tra la la".
