Definizione

  • Reed instruments that are free aerophones are sounded by a flow of air in which the reed is the primary vibrator. In sets of beating reeds the air-stream is directed against a set of lamellae, setting them in periodic vibration to interrupt the stream intermittently. The lamellae periodically open and close a set of apertures. The instrument is tuned by mechanical action on the lamellae. Such reeds may have a resonator, in which the air vibrates only in a secondary sense, not producing the sound; generally recognizable by the absence of fingerholes. The earlier reed stops of organs.
