Welcome to the Trombone Studio at the University of Colorado Boulder! Here you will find important information for current students as well as a place for the inquiring trombonist to find out more about us, and what it is we do.

The trombone studio at CU is an excellent group of students ranging from young freshmen through those pursuing the doctorate. We are supportive, collaborative and genuinely enjoy the shared experience of improvement as trombonists, musicians and humans.

Weekly private lessons, weekly trombone class and Trombone Ensemble provide the basis of our collective interactions. Additional enrichment comes from frequent guest recitals and master classes by some of the world’s leading trombonists: Joseph Alessi, Ian Bousfield, Craig Mulcahy and Christian Lindberg, to name a few. The sheer beauty of Boulder and the proximity of Denver with easy access to its flourishing arts scene complement a fully comprehensive College of Music within a world-class academic institution, the University of Colorado Boulder.

Potential students are encouraged to contact Bill Stanley directly.
