Check the following list for tips on how to present your material to a music publisher. The lyric sheet that accompanies a tape or CD and there must be one should be neatly typed and in a form that delineates the verses from the chorus and the bridge. Sometimes, double spacing will help to make it more easy to read depending on length. Always cue your tape up to the first song.
Nothing is more frustrating than listening to dead air.
I know of publishers who will shut it off if there's no song in the first five seconds of tape. Keep the space between songs, if there's more than one, to a minimum for the same reason. Erase any extraneous noises from the tape. That includes count downs, studio chatter, verbal intros, and heaven help me, an explanation of the song. The vocals must be upfront.
