mechanically striking a string or
tine (piano, electric piano, clavichord)

sound by being struck, including drums and cymbals,
or the section of the orchestra playing such
instruments.

Percussion instruments
are referred to as
membranophones if they
produce sound through the
vibrations of a stretched
skin or other membrane.

PLAYING DIFFERENT NOTES
Tuned by tightening or loosening the head of the
drum.
Tighter the drum, the higher the note.
The larger the drum, the lower the pitch.

Percussion instruments
are called idiophones if
they produce sound
through their natural
resonance when struck,
rubbed, plucked, or
shaken.

MAKING SOUND
Percussion instruments make sound by being hit.
Drums have a hollow body that amplifies the noise
of a stretched membrane being hit.

Maracas are shaken.
Bells resonate when hit.
Cymbals, just plain make a noise when they're hit.
