Final answer:
Pitch is the perception of the frequency of a sound wave, with higher frequencies resulting in higher pitches. Musical notes correspond to specific frequencies, and perfect pitch is the rare ability to identify these notes by ear.
Step-by-step explanation:
Relationship Between Pitch and Frequency
The frequency of a sound wave is directly related to its perceived pitch. Humans can discern the difference in pitch when the frequency of two sounds differs by at least 0.3%. For instance, sounds with frequencies of 500.0 Hz and 501.5 Hz are noticeably different in pitch. Higher frequency sounds have a higher pitch, such as the chirp of a bird, while lower frequency sounds, like the roar of a lion, have a lower pitch. Perfect pitch is the rare ability to identify musical notes by ear. In the context of musical notes, each corresponds to a specific frequency.
When the amplitude and frequency of a sound wave increase, the loudness and pitch of the sound are affected respectively. Loudness is increased with amplitude and pitch is increased with frequency.
