What is a melody in musical terms?

A melody in musical terms is defined as a sequence of notes perceived as a single entity. This means that when you listen to a melody, you hear a series of musical pitches that are organized in a coherent and recognizable manner, allowing it to be memorable and expressive. Melodies typically have a particular contour and character, often evoking emotions or representing musical ideas.

The other options do describe musical concepts, but they do not capture the essence of what a melody truly is. A combination of different notes played together refers more to harmony or chords, while a repeated rhythm indicates a pattern in rhythm rather than a melodic line. A style or genre of music describes broader categories and does not pertain to the specific linear arrangement of pitches we think of as a melody. Hence, the definition that a melody is a sequence of notes perceived as a single entity best encapsulates this important musical element.
