HOW IT PRODUCES SOUND

mechanically striking a string or

tine (piano, electric piano, clavichord)



plucking a string (harpsichord)




causing air to flow through

a pipe (organ)



strike a bell (carillon)



Percussion

the group of musical instruments that produce

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.
