I didn't keep up my triple tonging and now am having trouble getting it back. I try to play exercises from Arban's every day. One day I start at the end and work backwards and one day start at the beginning and go forward. I don't do them all, I do a lot of them though. I'm pretty good with the scales and chords, it's the simple stuff that I can't get. When I repeat the same note it sounds choppy or not even. If I slow it down everything is even. when I get fast it's tu tu ku. Any ideas? I've been back at it for about 2 months. Please don't tell me to get a teacher.
