Hello I bought a simple key less clarinet like this but I can only do the major scale from the bottom. How do I use properly the home behind ? Without it I can't make any sound, is there a technique ?
The high notes? I made it with 9 holes to use the upper hole semi-covered like a register key. You need a hole very close to the mouthpiece to change the register. But is difficult to get these notes and you need make changes of embouchure to play in tune, I also modified the mouthpiece
