Hello fellow recorder players, I recently fell in love with the sound of the tenor and bought one few weeks ago. (Aulos 511w) This is my first wind instrument. Eventhough i'm practicing everyday scrupulously following the instructions of my self-teaching book (can't find a teacher where I live) I'm still having a problem with the sound of my own play. Clearly,....it's unclear ! It is spluttering or crackling or whatever you would call it, my sound is not clear and if not pure (I'm just a newby) at least not on the way to be. I wonder where would that come from, I tried to modify the position of my lips, the strengh of my blow, but still.... If any of you could bring any advice, I would be very thanksfull. Fred.
