Hi everyone,

Welcome to my online store! I am excited to be sharing this tool with you. At this time, the book is only available digitally. Physical copies coming soon! I am offering a version for teaching studios that allows for sharing. If you buy a copy for individual use, please do not share with others. Wishing you all the best, and hope that you've been able to weather the pandemic safely.

"For any instrumentalist interested in reaching the next level, it is imperative to have facility with the necessary scales of your musical genre.  108 Scale Studies, Vol. I is a thorough examination of the scales classical trombonists need to stay at the top of their game. This book is helpful to both tenor and bass trombonists looking to hone their craft."
