The player's embouchure, lip tension, and air flow are used to play various octaves of a note. Pitches can be changed by altering the player's embouchure.
To change the pitch of a shaking instrument, add or detract from whatever material inside it forms the noise as it is shaken. Less material will give a higher pitch. More material will give a lower pitch.
Two ways that you can change the sound of an instrument are tuning or adjustment of the valves. Another way to change the sound of an instrument is to change your technique of blowing or bowing technique. I am sure there are more ways but here are some ideas!
Brass instruments have a brassy timbre due to the size of the bore (the hole), and how much emphasis is being put in to playing the instrument in order to generate the noise quality from the instrument.
The Koto, a Japanese instrument derived off the Chinese Guzhen, has thirteen strings. It has 13 strings and 13 movable bridges that can be adjusted before playing to change the pitch of the strings.
changing their embochure and tuning your insrtument
It depends on the instrument that they are playing.
They can change into coal
If you don't know what happens when there is pressure then your a down syndromes orangutang...
The clarinet keys are labeled with letters corresponding to the notes they produce. They are used to change the length of the instrument's air column, which alters the pitch of the sound produced when playing.
remains constant
A barometer is used to detect changes in atmospheric pressure, which can signal a change in weather. It measures the pressure exerted by the atmosphere and can provide an indication of incoming weather systems.
Pressure Indicator is any instrument that indicates pressure. Pressure Gauge is also a type of pressure Indicator. It is a mechanical device. Pressure indicators can work on mechanical deflection (in case of pressure gauge) or Piezo electric effect, change in capacitance, change in inductance etc. These are generally digital type instruments.
An altimeter is sensitive to atmospheric pressure and can show the altitude of the aircraft based on the change in atmospheric pressure from the aircraft ascending and descending. Likewise, a barometer, is sensitive to atmospheric pressure.
The trombone key is used to change the pitch of the instrument by extending or retracting the slide, which alters the length of the tubing and produces different notes.
A barometer is an instrument used to measure atmospheric pressure changes associated with warm fronts. When a warm front approaches, the pressure usually decreases, indicating the impending weather change.
Wind happens when there is a change in pressure in the atmosphere which causes air to rush to the lower pressure area, thus causing wind.
Boyles law "happens" when the temperature is held constant and the volume and pressure change.
