I just started playing flute about two weeks ago and I am have a little trouble trying to train my lip to get the octives out. I`ve played clarinet for close to 15 years and decided to pick the flute up because I always wanted to play. I can get the octives out its just difficult to get them out jumping from one to the other. Any ideas? I play all the time but have to give myself little breaks for my lip tightens. Could the brand of my flute have something to do with it as well. There is no brand on it, so I think it`s a real cheapo, but figured it would be good to start on.
