Music is meant to be listened with the heart, not only the ear. That is the part of music that appeals to the emotion. Emotion in music is sometimes lost when one only listen with the ears.Melody is a strange thing as it is most often the only part in music that make us recall certain piece of music. The rhythmic part does not play that role. Maybe because if we could recall a piece of music from childhood, the melody is what we remember. The rhythm is almost always inevitably associated with it in our mind, whether it's a fast or slow rhythm.
