S1: Music, like literature, is an art that deals with sound.
P: Literature makes use of words which are sounds.
Q: They also have meanings.
R: And the writer must be concerned with the effect produced by the sounds he uses.
S: But words are not only sounds.
S6: They refer to specific things other than themselves such as objects an ideas.

The Proper sequence should be:
