I was wondering how I should go about practicing long tones properly. I realize its something that I have never really done ( probably more boring than watching the grass grow for me tbh its torture) but I need to start doing some as my tone hasn't really gotten any better. Something I never did for my entire trumpet career up to like 3 weeks ago was play softly when practicing, thus I can't play soft AT ALL without sounding airy or being flat out not able to make a soft attack ( the attacking is really bad on notes below a g in the staff). So when I practice long tones am I supposed to play every note I can starting at like a g in the staff and then go down chromatically and then all the way back up to the extent of my range? I've heard a trillion different things concerning long tones, stuff like play them low, start middle then go down then go up, play them to improve your tone, play them soft, play them loud. Also how long should I hold them? Each note for as much breath as I have? is 8 counts at 60 tempo enough? is it really the more the better and is it just up to how much time I'm willing to put in to them? What's reasonable? so many questions . - Thanks.
