No. The composition IS the melody. It is the original written music, notes on sheet music.


In pop music, the arrangement is everything else. The backing tracks. Percussion tracks, the beat, guitar tracks, synth tracks, piano, effects, etc.

With the main vocals usually making up the composition.

Sometimes, the composer simply comes up with the melody, and the arranger decides what instruments go where.

Some people refer to this as the mix of a track (even though the term "mixing" means something else), but, hence why we have remixes.


So, at the most basic, for example, Ayu's M has an original composition/melody, and an arrangement.

A remix of M has the original melody, but has a different arrangement.


Or maybe a better example, over remixes, is Koda's ~eternity and love songs~ album. Those are covers, with all of the original melodies and compositions, but Koda changed all of the arrangements, so they are almost like new songs.
