Recurrent and painful shoulder and elbow problems have made me put aside by beloved trombone for the foreseeable future. Not wishing to give up my banding (or to become a shedbuilder ) I have started learning how to play a valved instrument (tenor horn, if you must know). However, it was suggested to me that I might try a valve trombone. I've always been led to believe that these are, somehow, not particularly acceptable. However, I found this on YouTube and, if they are in use by "serious" players, I wonder why they are not used instead of the slide variety in brass bands. What are your thoughts and what would be your reaction if someone turned up in your bandroom with one?
