Knowra Percussion instrument Percussion instrument A musical instrument that produces sound when struck, shaken, scraped, or otherwise set vibrating by an action. Its sound may have a definite pitch or an indefinite one.
Idiophone : A percussion instrument whose vibrating body produces its sound without stretched strings or membranes. Its body itself vibrates in instruments such as bells, cymbals, and xylophones.
Drumhead : A stretched membrane that vibrates to produce sound when struck or otherwise excited. Its tension, size, and material shape a drum’s response and tone.
Drum kit : A collection of drums and cymbals arranged for performance by one player. It combines multiple percussion sounds into a single instrument setup for popular music.
Definite-pitch percussion : Percussion instruments that produce tones perceived as having stable, identifiable pitches. These instruments can play melodies and harmony, unlike percussion with indefinite pitch.
Membranophone : A musical instrument that produces sound through the vibration of a stretched membrane. Drums make sound when a struck membrane sets the instrument’s air and body vibrating.
Bell : A hollow, usually metal instrument whose vibrating body produces a resonant sound when struck. Its shaped shell vibrates in complex modes that create a distinctive, sustained tone.
Timpani : Large orchestral kettledrums whose pitches can be adjusted by changing membrane tension. They provide resonant, tunable low notes in orchestral music.
Indefinite-pitch percussion : Percussion instruments whose sounds do not have a stable, identifiable musical pitch. This category highlights percussion’s rhythmic and textural role beyond tuned notes.
Resonance : The reinforcement of vibration when a system responds strongly to frequencies near its natural frequencies. Resonant bodies and cavities shape a percussion instrument’s loudness and tone.
Mallet percussion : Percussion instruments played by striking bars, plates, or other surfaces with handheld beaters. Mallet hardness and striking position alter the sound produced by the instrument.
