So, I've just finished my Grade 8 and want to consolidate before going for the Diploma. My main problem is with range. I went all the way to grade 7 by puffing my lips to increase the ambient pressure and therefore air speed, allowing me to reach the notes but I'd tire quicker. After changing teachers, my current one (whom I now must leave unfortunately) rapidly beat the habit out of me :L but unfortunately when you've been missing out on all the strengthening 8 years of playing can provide when you play properly, it ends up leaving you far behind the crowd with range and stamina in the end. So I was just wondering what and where can I find the best exercises to push me into shape? I know it may take years, but I'd like to know that I'll be working with a method advocated by you pros as otherwise I'd be tempted to change if I didn't feel any improvement. So if anyone can recommend anything, I'd jump on it to be honest. I love playing and just wish I could do it for longer. Thanks!
