I was wondering what you all do for your warm up routines. How long on average does your warm up last. Sometimes I'm afraid I'm not warming up long enough... I start with mouthpiece buzzing and then long tones. I then usually do some lip slurs and scales. All in all, it last about 5-10 minuets. Does anyone have some advice on what I could add to my routine, or is it just fine how it is?
