What does pitch refer to in music?

In music, pitch refers to the perceived frequency of a sound, which determines how high or low a note sounds. It is fundamentally connected to the frequency of the sound wave, which is measured in hertz (Hz). Higher frequencies correspond with higher pitches, while lower frequencies yield lower pitches. This concept is essential for understanding melodies and harmonies, as different pitches create the tonal structure of music.

The other options refer to different musical elements: the speed of the music relates to tempo, the volume level of a sound corresponds to dynamics, and the pattern of musical notes describes rhythm. Each of these aspects contributes to the overall understanding of music, but they do not define pitch.
