You want a wooden clarinet because wood resonates. It is responsive in your hands. You can feel the potential of improved quality the second that you excite that standing column of air into motion by embouchure and diaphragm control. In order to chase this carrot down, you need to go to music storeS and play ALL OF THEM. Grenadilla wood is amazing stuff. It can be shaped into the best instrument ever, with sweet earthy tone and real character...or it can suck. You will discover differences in responsiveness even with instruments that came off the assembly line at the same time. It`s because natural, real wood responds in different ways from grain to grain and from tree to tree. You have to find the instrument that sings to you. Is it a Buffet? Selmer? Noblet? Boosey& Hawkes? Yamaha? When you find it, you tell us! Remember this, my young friend...it`s not the car that matters/ It`s all about how well you drive what you have... Good luck with the girl!
