Sound is the vibration of air or another me-
dium (like water). When you speak, sing, or
clap, you create sound waves that radiate out
into the environment. Every sound has its own
“signature” that is called a waveform.
WHAT IS
SOUND?
PITCH VS. FREQUENCY
Frequency and pitch are similar, but not the
same! Frequency can be measured scientifi-
cally, while pitch is dependent on individual
perception. You can distinguish pitches as
being “higher” or “lower.”
AMPLITUDE
Amplitude relates to the change in the peaks
of waveforms and is perceived as the loudness
of a sound. The higher the amplitude of a
waveform, the louder it sounds.
TIMBRE
Timbre (pronounced tam-ber) is what differ-
entiates sounds of the same pitch. It is what
makes a violin and a flute sound different…
or your friends’ voices!

PITCH
Pitch is how a person perceives the frequency
of a vibration. Every person perceives pitch
differently and some have a better sense of
pitch than others. Sound can generally be
categorized as pitched or un-pitched.
