Biwa-gaku

Biwa-gaku is the chanted-narrative tradition built around the biwa, a short-necked pear-shaped lute introduced to Japan from China in the eighth century. Several distinct sub-traditions exist: heike biwa (for chanting the Tale of the Heike), satsuma biwa (a fifteenth-century Kyushu warrior-class tradition) and chikuzen biwa (a later Meiji-period popular form). The standard texture is one voice with one biwa, with the lute punctuating the chanted narrative with percussive plectrum strokes and brief melodic fills between vocal lines.

The biwa arrived in Japan as a court instrument but moved into popular religious practice through the moso (blind monk) tradition. The Tale of the Heike — the medieval war chronicle of the Genpei War — was chanted from the thirteenth century onward by guilds of blind biwa monks (biwa hoshi), making the instrument inseparable from the warrior epic. Satsuma biwa was developed in the fifteenth century in Kyushu for samurai self-cultivation; chikuzen biwa is a nineteenth-century synthesis that admitted female performers. Recent revivalists include Yamashika Yoshiyuki and Yumiko Tanaka.

The biwa is played with a large fan-shaped plectrum (bachi) that strikes the strings hard — the attack is percussive as much as melodic. Listen for the rests: the chanted vocal lines pause frequently, and the lute fills those gaps with short rhythmic flourishes rather than continuous accompaniment. The tuning system uses very wide frets, so the player bends the strings sharply behind the fret to produce intermediate pitches.

Recordings of Tsuruta Kinshi (1911–1995) on satsuma biwa, particularly her readings of Heike repertoire, are the canonical document. Yamashika Yoshiyuki's recordings of the older heike biwa tradition are a deeper archival reference.

Tsuruta Kinshi's biwa playing inspired Tōru Takemitsu's November Steps (1967), a piece for biwa, shakuhachi and orchestra commissioned and premiered by the New York Philharmonic — one of the few twentieth-century classical works to put a biwa player at centre stage with a major Western orchestra.
