Pitch refers to the perceived frequency of a sound, determining how high or low it sounds to the human ear. It is measured in Hertz (Hz), with higher frequencies producing higher pitches and lower frequencies resulting in lower pitches. For example, a flute typically produces higher pitches, while a trombone generates lower pitches. In music, pitch is essential for creating melodies and harmonies. Each note corresponds to a specific pitch, and musicians use various instruments, such as pianos and guitars, to produce these sounds. Understanding pitch helps in tuning instruments and composing music effectively.
