【Gagaku】
The word gagaku refers broadly to ancient court music and dance that has been performed since the eighth century and is Japan’s oldest musical tradition. Originally introduced from China and the Korean Peninsula, gagaku was mostly performed at events in the imperial court and at temples and shrines. Over centuries of cultural exchange and the gradual evolution of the genre, it has retained the instruments and styles that most strongly resonated with Japanese tastes. Gagaku musicians and dancers of today follow the traditions of the court musicians of the Heian period (794–1185), and throughout history, the genre’s popularity has largely coincided with the power and influence of the court.
The traditional gagaku ensemble includes three wind instruments, two stringed instruments, and three percussion instruments. In a gagaku composition, several instruments play interpretations of the melody at the same time. Adherence to ancient tradition is strong in the art, and contemporary compositions are rare.
Hikone Collection of Gagaku Instruments
The museum collection of gagaku instruments, many of which were gathered by the daimyo Ii Naoaki (1794–1850), can be considered one of the most extensive collections in Japan. It is not uncommon for especially well-crafted gagaku instruments to be given individual names, and the fine bags and boxes used for storing them are often works of art themselves.
Wind Instruments
The three main wind instruments in gagaku are the hichiriki, the shō, and the ryūteki. The hichiriki, a small, nine-holed pipe with a double reed, is one of the main melodic instruments in gagaku.
Originally from China, the shō is a Japanese free-reed musical instrument made up of seventeen slender bamboo pipes, each with its own reed, and is said to resemble a phoenix (ho-o) in both appearance and sound. Like a harmonica, the shō can be played by both inhaling and exhaling.
The seven-holed bamboo ryūteki (dragon flute) is used for playing Chinese-style songs in particular. The sound of the ryūteki is said to resemble the voice of a dragon.
Stringed Instruments
The primary stringed instrument of the gagaku ensemble is the biwa, a short-necked, four-stringed, fretted lute originally from West Asia. It is supported by the sō (or koto), a long, thirteen-stringed zither. Gagaku musicians play both of these instruments using a paddle-shaped plectrum. Generally, the biwa plays an abstract melodic line within the song. The sō adds short, repeated melodic phrases.
Percussion Instruments
The three percussion instruments strengthen each phrase of the melody and anchor the rhythm. The large hanging drum (taiko) of the gagaku ensemble provides the main accents. The kakko, a small, braced drum, and the shōko, a small bronze gong, add to the rhythmic complexity. The kakko also signals tempo changes and announces the end of a piece.
