Final answer:
The melody of a piece of music refers to the horizontal and linear presentation of pitch. It is a sequence of notes that moves horizontally across the musical landscape, different from harmony, rhythm and dynamics.
Step-by-step explanation:
In the context of music, the melody refers to the horizontal and linear presentation of pitch. The melody is essentially a sequence of notes that are perceived as a single entity, giving a song its recognisable tune. The flow and arrangement of these notes in a linear fashion determine the melody of a piece. It varies as it moves horizontally across the musical landscape, making it distinct from other musical elements such as harmony, which refers to the vertical stacking of notes, dynamics which refers to the volume of the piece, and rhythm which refers to the timing of the music.
