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.
For tuning, the notes of the flute can be compared to the notes of a piano, pitchpipe, or other tuning instrument. Or you can simply tune the notes of the flute to each other, in the do-re-mi pattern, with the low note as do. Read the book! Simple Flutes A Guide to Flute Making and Playing By Mark Shepard.rom there, you will have to experiment with final placement and hole size, using tuning techniques such as the ones weâll now discuss. (For more advanced techniques, see my book, Simple Flutes .). Here are the two most important rules for tuning: A hole will give a higher note if it is placed closer to the mouthhole.
