Pitch and Frequency
The FREQUENCY of a Tuning Fork
• Tuning forks make a sound when they vibrate.
• Tuning forks are marked with a number.• The number tells you how many times the
tuning fork vibrates in each second.• Scientists call this the FREQUENCY of the
sound the tuning fork makes.• The units of frequency are hertz.
The PITCH of a note
• Musicians don’t use the word frequency.• Instead they talk about the PITCH of a
note.• The pitch tells you how high or low a note
sounds.
Notes on Frequency and Pitch

• Scientists use the word frequency to tell how many times an object vibrates every second. Frequency is described by a number and its units are hertz.
