Question

Although they are commonly labeled with letters, ______ can also be measured by sound waves per second, using Hertz or Hz.

a) pitches
b) beats
c) rhythms
d) meters

Answer 1

Pitches, labeled with letters in music, can also be measured using units of frequency called Hertz (Hz); they represent the number of sound waves per second.

Step-by-step explanation:

The term commonly labeled with letters that can also be measured by sound waves per second using Hertz or Hz is pitches (option a). In music, pitch refers to the perception of sound frequencies. Different pitches are commonly labeled with note names like A-sharp, C, or E-flat. However, the frequency of these pitches can be quantitatively measured in units called Hertz (Hz), which specifies the number of sound wave cycles per second. For instance, the pitch of middle C in music is typically about 261.6 Hz. Sounds at higher frequencies have higher pitches, and vice versa. The range of human hearing spans from about 20 to 20,000 Hz, within which the pitches of most musical notes fall.
