The lips are pressed together and air pressure from our lungs makes them vibrate. The length of the resonator (the Trumpet itself) is adjusted with the various valves, changing the resonant frequency and thus the pitch. You can make more than one pitch, usually in steps of a fifth, by changing the pressure of your breath and/or lips.
a high sound
Wind instruments use air to create vibration which creates sound. Percussion instruments create sound through striking a Stretched membrane which produces sound or by the vibration of the instrument as a whole.
The vibrations from your lips are what creates sound
Most percussion and string instruments operate of vibrations to produce sound. Drum heads, xylophone bars, strings and reeds all vibrate on instruments that use them to produce sound.
The strings.
Sound is vibrations in a physical medium (usually air). Sound is produced by a release of energy that causes a vibration in the medium. Sound can not therefore be in a place where there is no medium (empty space).

The same way normal drums do--the vibration of the top causes sound.
fulke
the closing up of the tricuspid and bicuspid valves produce the ' lub' sound while closing up of semi lunar valves produse the ' dub ' sound
what sound does drum produce
Sounds like that answer would be the Vocal Chords.
sound waves dont produce vibrations, vibrations are sound waves.
Yes sound does produce waves. These special waves are called sound waves.
if you plunk it with your fingers you produce sound
what causes sound when you speak
This is known as 'Sound Cancellation' or deconstructive interference. It occurs when two waves 180º out of phase of and of equal magnitude combine. The resulting wave has zero magnitude and thus cannot be heard.
