The speed of sound is the distance travelled per unit time by a sound wave as it propagates through an elastic medium. In dry air at 20 Â°C (68 Â°F), the speed of sound is 343.2 metres per second (1,126 ft/s; 1,236 km/h; 768 mph; 667 kn), or a kilometre in 2.914 s or a mile in 4.689 s. The speed of sound in an ideal gas depends only on its temperature and composition. The speed has a weak dependence on frequency and pressure in ordinary air, deviating slightly from ideal behavior.
A flute is a musical instrument that produces sound when a stream of air is directed against the edge of a hole, causing the air within the body of the instrument to vibrate. Most flutes are tubular, but some are globular or other shapes.
Construction. First, a panshot along the three types of flute - C flute (held), alto and bass: Now, the piccolo: differences with the flute construction of the instrument the registers of the piccolo. The flute has three joints: footjoint, body and head joint How the sound is produced How tuning is adjusted The first and second octave on the flute The third octave. The alto flute: construction of the instrument sound production the low register the high register. The bass flute: construction dynamic range the low register the middle and high registers playing the bass flute
