How to Play the Koto Instrument

Learn how to play the Koto

This koto instrument is positioned horizontally before the player, who sits on the floor or a low stool.

Sound is produced on the koto by plucking the strings with finger picks, traditionally made from ivory, bamboo, or plastic.

These picks are worn on the thumb, index, and middle fingers of the right hand. The left hand is used to press the strings against the instrument’s body or to manipulate them above the bridges to create vibrato and other expressive sound effects.

This interaction between the picks and the strings generates the koto’s distinctive, ethereal sound, which can convey a wide range of emotions, from the tranquil to the dramatic.

The movable bridges, known as kotoji, play a crucial role in the instrument’s sound production. Positioned under each string, these bridges determine the pitch and can be adjusted by the player to tune the instrument to different scales and modes.

The technique of playing the koto involves a delicate balance of hand coordination, precise timing, and emotional expression. Players must master various plucking methods, string-bending techniques, and the art of bridge adjustment to fully explore the instrument’s musical potential.

The Koto Historical Development

Now that we examined the long historical development of the koto, lets now explore our understanding of the important parts of the modern instrument which produce the traditional musical sound.

Koto Instrument Description

Each part of the koto is carefully constructed from specific materials. Each contributes to its unique sound and aesthetic. The main components include the soundboard,

  • Soundboard: At the heart of the koto’s construction is the body (or soundboard), primarily made from Paulownia wood (known as “kiri” in Japan). Paulownia is chosen for its light weight, fine grain, and ability to produce a resonant sound, making it ideal for the koto’s large, hollow body. This wood’s natural properties ensure that the koto can produce its characteristic warm, rich tones.
  • Strings: The strings, traditionally made from silk, have evolved with the introduction of modern materials such as nylon or polyester, offering durability and a consistent tone.
  • Kotoji bridge: Each string runs over movable bridges called kotoji, which are crucial for tuning. The kotoji, made from bamboo or ivory, can be adjusted along the length of the instrument to change the pitch of each string, allowing for a versatile range of sounds.
  • Plectrums: Worn on the fingers of the player, they are traditionally made from ivory or tortoiseshell, although modern alternatives include plastic. These picks are essential for plucking the strings, and their material can influence the timbre and attack of the notes produced.
  • Decoration: In addition to the primary materials, decorative elements such as inlays of mother-of-pearl or lacquer work can adorn the koto, reflecting the craftsmanship and aesthetic considerations in its making. These decorations do not affect the sound but signify the instrument’s cultural value and the artisan’s skill.
