12/60 - Play Along 2 - Quarter Tones and Swing
This study could be a first introduction to microtones for clarinet students. It's a playful short etude dedicated to Lionel Liebe, a former clarinet student of mine who took part to 60/60. Have fun with the quarter tones (and no, you don't need a quarter tone clarinet to play this tune)!
Performers are Petra Stump and Heinz-Peter Linshalm. They recorded several albums. Online, you can get Pierluigi Billone: 1+1=1
More clarinet quarter tones
For advanced students, a great clarinet solo with quarter tones is If by Pascal Dusapin. I was lucky to learn it with Armand Angster at Conservatoire de Strasbourg. I highly recommend to meet and learn from him!
