In this lesson we will learn about pitch.
Pitch is the relative highness or lowness of a sound. It's important to understand what sound is to understand pitch better sound is the vibration of air molecules moving through the air to your eardrum.
The speed of the vibrations is called the frequency sound frequencies are measured in hertz musicians tune the pitch a to the frequency 440 Hertz since the range of frequencies humans can hear is 20 to 20,000 Hertz we need a simpler system of labeling the frequency range. Pitch is the musical label of a frequency.
PITCH LETTER LABELS
We only need the first seven letters of the alphabet to describe any note in the frequency range. As frequencies move higher up the pitch label moves forward through the alphabet looping around as necessary: a-b-c-d-e-f-g-a. As frequencies move lower down the pitch label moves backwards through the alphabet again looping around is necessary a-g-f-e-d-c-b-a.
