As a beginner I thought I would start off with a low cost clarinet and if I like the instrument I can move to an up price Yamaha like my different saxes. I notice that even with the barrel, MPC etc. pushed right in the clarinet still plays as shown on the meter very, very flat. I thought this was my embouchure but on trying another clarinet I found it to be spot on. Is this normal for lower cost clarinets and is the only solution scrapping or buying a shorter barrel.
