Question

What is the most memorable part of a musical composition

A) The key signature
B) The melody
C) The accompaniment
D) The texturing

Answer 1

I believe it would be B! The Melody!
Stand back and look at it in the eyes of someone that's not as music savvy - the thing that truly makes you relax and turn to bliss - is the melody. You tend to focus on it, listen for it.
I hope all is well, and you pass! Good luck, rockstar! (:

Answer 2

The most memorable part of a musical composition is B the melody.
