The pitch is changed on a trombone by moving the slide or changing your ombisture.
Pitch is changed by altering the frequency of a sound wave, with higher frequencies resulting in higher pitch. Loudness is changed by adjusting the amplitude or intensity of a sound wave, with greater amplitude producing louder sounds. Both pitch and loudness can be modified by factors such as distance, medium of transmission, and physical properties of the sound source.
probably, probably not
The pitch of any violin string is changed depending on which spot on the fingerboard a finger is placed.
The pitch can be changed by tightening or loosening the lips (embouchure), depressing a valve or valves and by moving tuning slides. The pitch can also be affected by temperature and by the density of the gas being blown through it. Try playing a trumpet with a lungful of helium.
Volume is controlled by air flow, and pitch is changed with the valves and lip configuration.
When a young man's voice breaks it becomes noticeably lower in pitch. Has the pitch of your voice changed?
In the case of a guitar string, the tension.
Modern electronic sirens change amplitude and pitch. Older sirens produced tones that changed in amplitude (volume) but were changed in pitch by their motion relative to the listener: increasing in frequency as they approached and decreasing in frequency when they moved away. This is called the Doppler Effect.
One way baseball has changed is that they use to not let black people play now they do. Another way it that they have outlawed the spitball a type of pitch
The vibration is changed by either reducing the length of the string (holding it down on a fret) or changing the tension of the string.
you can tune the front and back of the bass or you can put "O" rings on the heads of it.
