About us


SMARTassMusic is a small independent music company, run by professional musician James (Jim) Treweek and provides high quality production music, original composition and written music arrangements.

Frustrated by the consistently poor quality written arrangements that most “jobbing” musicians have to work with, SMARTassMusic was formed in 2000 in order to provide clear, intelligent, cost effective written arrangements to musicians and producers. We now provide written music for studio recording, theatre and concerts around the world and our stock music used in videos and broadcasts in most countries.

James trained classically in Piano & Clarinet and studied Jazz at University with Leon Cohen-one of the UK’s most knowledgeable Jazz musicians and an experienced film and TV composer and arranger.
After gaining a degree in Music he returned to Middlesex University to teach Jazz piano for a further 7 years.
