ulreed

The ulreed is a unique and experimental musical instrument that combines elements of the reed organ and the ululator, a type of wind instrument. Created by composer and instrument designer **Ben Johnston** in the 1960s, the ulreed is designed to produce a broad spectrum of sounds, ranging from deep, resonant tones to high-pitched, ethereal pitches. Unlike traditional reed organs, which rely on a single reed for each note, the ulreed incorporates multiple reeds per key, allowing for a richer, more complex timbre.

The instrument features a keyboard connected to a series of metal reeds that vibrate when air is forced through them. The reeds are arranged in a way that enables the player to produce both sustained notes and rapid, percussive-like articulations. The ulreed’s design also allows for the manipulation of pitch through the use of a sliding mechanism, similar to that of a slide whistle, which can alter the length of the reed chambers and thus the pitch of the emitted sound.

The ulreed has been used in experimental and avant-garde music, particularly in compositions that explore extended techniques and unconventional sound production. Its distinctive timbre and expressive capabilities make it a favored tool for musicians seeking to push the boundaries of traditional instrumental music. While not as widely known as other instruments, the ulreed remains a niche but influential instrument in contemporary experimental music circles. Its construction and operation require skill, and it is often played by musicians with experience in both wind instruments and electronic music.
