what is an example of a double-reed instrument?
oboe
a single-reed instrument is a woodwind instrument that uses only one reed to produce sound. the very earliest single-reed instruments were documented in ancient egypt, as well as the middle east, greece, and the roman empire. the earliest types of single-reed instruments used idioglottal reeds, where the vibrating reed is a tongue cut and shaped on the tube of cane. much later, single-reed instruments started using heteroglottal reeds, where a reed is cut and separated from the tube of cane and attached to a mouthpiece of some sort. by contrast, in a double reed instrument (such as the oboe and bassoon), there is no mouthpiece; the two parts of the reed vibrate against one another. reeds are traditionally made of cane and produce sound when air is blown across or through them.

the work is composed in three sections. the first section is a cycle of phase shifts of the basic unit between the live instrument and one instrument on the tape . the reed instrument recorded on the tape repeats the basic unit in a fixed tempo, while the instrumentalist begins a cycle of phase shifts consisting of the soloist repeating the basic module a certain number of times, then accelerating the tempo until the shift against the steady part (tape or accompanying reed instrument) is increased by one eighth note, and then resuming the initial tempo for a certain number of repetitions in a constant relationship with the tape. the instrumentalist then accelerates again until the time lag is increased to a quarter note. this process is repeated until the starting point is reached once again, which is to say it returns to a unison (in phase) with the tape, which marks the end of the first cycle of phasing .
