kishun - 古界 ｜ Kokai (CS+DL)

kishun is a duo: ISHIKAWA Ko, player of the shō (mouth-organ), and NAKAMURA Kahoru, player of the gaku-biwa (Japanese court lute). Since 2015 they have used only shō and biwa. Their idea is to bring out the hidden sound in what they call “gagaku without melody.”

Gagaku is the ancient court music of Japan. It is more than a thousand years old. In the Heian period, nobles gathered old songs and dances from Japan and pieces that had come from Korea and China between the 5th and 9th centuries, and shaped them into one art. As gagaku took root in Japan, it was arranged and rebuilt. The form we hear today is unique to Japan. By the Heian era, it was already close to its present shape. Gagaku lives in two worlds: as court music at the Imperial Palace, and as sacred music for rites and festivals at temples and shrines. Because of this history, it was kept by nobles and professional musicians, away from the taste of ordinary people. Its instruments and dances are very different from most other Japanese traditions.

Gagaku has four main kinds: bugaku (dances, including those from the continent), kangen (an instrumental ensemble), kuniburi-no-utamai (old songs and dances from Japan), and utamono (vocal music from the Heian period). Among these, kangen is rare in Japan: it is a full orchestra made only of instruments. Most other Japanese music centers on singing. When there is instrumental playing, it is often in small groups or as support for theater and dance. Kangen stands apart.

The kangen ensemble is called “three winds, two strings, three drums.” The winds are shō, hichiriki (double-reed), and ryūteki (transverse flute). The strings are biwa and so (zither). The drums are kakko, taiko, and shōko (gong). The hichiriki and ryūteki carry the melody. The shō wraps them in chords. The string parts frame the rhythm. Kishun plays only shō and biwa, both in classic pieces and in improvisation.

The shō is a free-reed mouth organ with 17 bamboo pipes of different lengths and pitches. Each pipe has a small metal reed. In the classic style, players do not use tonguing. They shape phrases with breath. The shō is not loud. In ensemble it plays long, steady chords called aitake. These chords color the melody and show the center of the mode (scale).

The gaku-biwa is a lute. Today it has four strings and four frets, and is played with a plectrum. Its back is flat and the body is shallow. Its sound is strong at the start, then fades quickly, with almost no ring. For this reason, the biwa speaks more in rhythm than in harmony.

kishun leaves out the melody instruments of kangen. They focus on the shō, which builds a field of sound through aitake chords, and the biwa, which draws the rhythm. This is their experiment: to bring forward the voices that hide behind the melody. With the skill of two masters, they reach this goal. Sounds that the full gagaku ensemble often covers without notice step into the foreground and speak to us in a fresh, striking way.

(*1) ISHIKAWA Ko — Studied shō and gagaku song with MIYATA Mayumi, BUNNO Hideaki, and SHIBA Sukeyasu. He began performing in 1990. He plays classic and new works with Reigakusha, a well-known gagaku group, and also performs as a soloist. He has taken part in many projects with artists such as SAKAMOTO Ryuichi and Evan Parker. He is also active in free improvisation.

(*2) NAKAMURA Kahoru — While at university, she met the revival of Bankaso (the oldest known biwa score, reconstructed by SHIBA Sukeyasu) and began to study gagaku. She studied ryūteki with Shiba Sukeyasu, and gaku-biwa and umai (right-dance, a style with roots in the Korean peninsula and northeast China) with YAMADA Kiyohiko. A member of Reigakusha, she has performed since 1990 at festivals in Japan and abroad, and as a soloist. She also works to bring lost classic pieces back to li
