The act of song writing is a very
personal experience. It can be
shared by a co-writer(s) or be an
individual vision. If it is purely for
one's self gratification there are no
particular "rules" to be followed,
but if a song is meant to be
"pitched" to an A&R rep (artists &
repertoire representative for
publishing or record companies)
there are some guidelines that
should be considered.
