TYSA-Hammond Ashley Bass Workshop

Learn more about the TYSA-Hammond Ashley Bass Workshop, a fun intensive for bassists of any age or experience level!

July 9–12, 2024 • Pacific Lutheran University

The TYSA-Hammond Ashley Bass Workshop welcomes double bass players of all ages and levels of experience to learn from legendary bass pedagogue Jeff Bradetich and from Washington’s top bass teachers. Whether you are new to the instrument or a performance major in college, we invite you to explore the double bass through a highly concentrated study of technique-building exercises, orchestral excerpts, masterclasses, all-bass chamber music, jazz instruction, faculty recitals, and more!

A teacher in-service bass intensive is also offered – this track is designed specifically for teachers who primarily play other instruments and would like to further develop their bass skills for the classroom.

History of the Workshop

The Hammond Ashley Memorial Double Bass Workshop has helped hundreds of bassists improve their skills since 1993. Mr. Ashley attended the very first workshop, passed away shortly thereafter, and the following years have been dedicated to his memory. Under the direction of internationally-renowned double bass soloist and pedagogue, Jeff Bradetich, bassists from age 8 to 78 have attended the workshop and benefitted from his influence and teaching. The faculty for the workshop has included bassists from the Seattle Symphony, the Oregon Symphony, the San Francisco Symphony, the Cleveland Orchestra, and many premier regional bass teachers. Some attendees are now performing in major orchestras and teach bass themselves. From beginners to developing professionals, and every bassist in between, all are welcome to share the love of our instrument – the double bass – at this workshop.
