I hate my clarinet vibrato sound. I don't spend enough time on the instrument to get a really good sound, but it shouldn't be that hard to get a klezmer sound. I teach sax vibrato, to so many people. Believe it or not, the reason I teach it to so many saxophonists is because of the many, many times we are required to double a flute or oboe in concert band. A slight (very slight) classical vibrato can help with the inherent intonation challenges of that kind of double. So I need to research this and that will be my January 2018 project. How close to the Eddie Daniels sound can I get. The sad part is that many of the saxophonists that I have taught to use vibrato, especially for soloing in a concert band, now do it better than me!!! Just goes to show you that I'm not practicing enough.
