Hi, I'm just wondering what are your experiences with off horn exercises? It happens a lot to me that I have days that I can't practice, but there is some spare time when I can't really access the horn. I have read something but there are a lot of opinions on the net. I am not searching for an ultimate thing that would same to practicing on a horn, but something is better than nothing, right. What do you suggest? - free buzzing - pencil exercise - ... Can it be overdone or likely to ruin my embochure as some have written? What pattern should I use? Thank you... M.
