Five-key flute Five-key flute The five-key flute is a musical instrument once common in school marching bands, and composed of wood with metal keys. It is a transposing instrument, most commonly in Bb, this variant being known as the Bb flute and sounding one tone below the orchestral piccolo. The next most common variant is the Eb flute, sounding a fifth below the Bb flute and used as its bass instrument in band harmonies. It is now often found in British military corps of drums, often playing various regimental marches. As the name suggests, the five-key flute most commonly has five keys,
Irish flute Irish flute players tend to strive for a dark and reedy tone in comparison to classical flautists. Though most commonly pitched in the key of D, simple system flutes are available pitched in other keys, and are often heard in Irish music pitched in E flat, B flat and C. Although referred to as a D flute, this is a non-transposing instrument, so if you finger C, a concert-pitch C is sounded. The name D-flute comes from the fact that the simplest 6-hole wooden flute has D as its lowest note and plays the scale of D without any cross-fingering.
