Trailer or song structure?

Hi Rob,

Just saw this in one of the listings and was reminded of the advice you gave me about writing full trailers. I asked the question on the Taxi show on monday as well and Michael said that trailers have been more and more written as one piece.

TAXI Tip: Film Trailers almost always happen in three “acts,” or sections. Trailers typically last about 2 to 2.5 minutes in total length. Act One starts at the beginning. Act Two usually comes in around one-minute (could be a bit earlier or later), and Act Three usually comes in about 30 seconds later and ends with a big build/crescendo leading to a buttoned or stinger ending.

I guess I'll have to learn so I know what I'm doing next time.
Thanks again for your advice.

Benjamin
