Which musical element is primarily concerned with pitch?

The musical element that is primarily concerned with pitch is melody. Melody refers to a sequence of notes that are perceived as a single entity; it is the tune of a piece of music that is often the most memorable part. Melodies are constructed from pitches arranged in a specific rhythmic pattern, which allows them to stand out and be distinctly recognized by listeners.

In contrast, rhythm pertains to the timing of notes and how they are organized in a sequence, but it does not inherently involve pitch. Texture refers to the layers of sound in a piece of music, including how many voices or instruments are involved and how they interact, but it doesn't focus on pitch alone. Form describes the overall structure or layout of a musical composition, such as how sections are arranged, but it does not address the individual pitches used in the piece. Therefore, melody is the element that directly concerns pitch, giving it a central role in music-making and appreciation.
