Music expresses that which cannot be put into words and that which cannot remain silent
Avoid stock expressions (like the plague, as William Safire used to say) and repetitions. Don't say that as a boy your grandmother used to read to you, unless at that stage of her life she really was a boy, in which case you have probably thrown away a better intro. If something is worth hearing or listening to, it's very probably worth reading. So, this above all: Find your own voice.
