Play the Erhu in GarageBand for iPhone
The erhu is a traditional Chinese instrument with a short body and a long neck. The strings are tuned in fifths. The bow is never lifted from the strings, but passes between them, producing a continuous, voice-like sound. Playing styles include glissando, grace notes, trills, vibrato, and a characteristic horse effect, which uses upper glissando harmonics and deep vibrato.
