@Vic Wheeler ok, I did, not just reclining, but lying on my back! What i noticed - I was happy to find notes that matched his, at times (yes, used chromatic to find them). I would get stressed when trying to go into higher notes... then would relax and just play (sometimes thinking - oh, Vic would probably want me to be recording this, but I wasn't.) I also practiced holding notes longer, I think you said that lying on my back is good for that.. I still mostly only felt comfortable in my limited range, which was ok.. oh - and my left arm started tiring (right elbow I think was on the floor.) Also - was dizzy when I got up afterward! Thanks, see you later.
