Master the Clarinet with a Community of Music-Loving Adults 

After playing clarinet professionally for years (Broadway, Philadelphia Orchestra, Carnegie Hall), I founded Clarinet Ninja to teach adults who love music. Join a group at your level and learn with fellow clarinetists in a supportive, enjoyable environment.

I've been lucky enough to play and teach clarinet everywhere from Broadway pits to elite music schools. I built Clarinet Ninja for adults who love music, clarinet, and want to get better.

 

The Problem Isn't Practice 

You can practice alone for years and still feel stuck. The right teacher shows you what's working (and what's not). The right group keeps you accountable and makes learning fun.

"Jay has many insights on the clarinet both musically and technically.  Through his experience as a performer and teacher I have been able to add many new tools to my playing which helped me perform my first recital in 45 years at the age of 66."

I'm Jay Hassler

I've been lucky to have an amazing clarinet career: Broadway, major orchestras, Carnegie Hall, and just about everywhere else you can play clarinet professionally.

When the pandemic stopped live performances, I started teaching adults who chose the clarinet because they love music, and I found out I loved doing it!

So I built Clarinet Ninja. I teach the same professional techniques I learned performing at the highest level, but structure them for adult learners who want better tone, solid technique, and a supportive community.
