I wanted to create an ensemble to teach double tonguing and thought that a rock style piece would be a fun way to do that.   Most of the possible double tongue variations are present.  This piece is a septet, but it is written like a trumpet trio with a four part trumpet accompaniment.  The trumpet 4-7 parts are quite a bit easier as the double tonguing is featured in the top three parts.  The attached recording is meant to be a basic resource only.  (The Finale trumpet sounds are not that great!)
