Harmony refers to the combination of different notes played simultaneously, creating a richer and fuller sound. It provides the background and support for the melody and helps to create the overall structure of the music. Harmony is often created by chords, which are groups of notes played together.
Melody, on the other hand, is a succession of single notes that create a distinctive tune or musical line. It is the main part of a musical composition that listeners can easily remember and hum. Melodies are typically played by a single instrument or voice and are the most prominent and memorable part of a song.
In summary, harmony refers to the combination of notes played simultaneously, while melody refers to the sequence of single notes that form a tune. Both are crucial elements of music that work together to create a complete and engaging musical experience.
