I am a 76 year old clarinetist with mild, but yet advancing, arthritis in my right hand. I want to plan for pursuit with music so that five years from now I can still enjoy this passion. I can imagine placing my arthritic right hand in the bell of a horn and still being dexterous (oxymoron?) with my left hand. I've yet to even touch a horn, but I bought a mouthpiece and stuck it into a ten foot piece of vinyl tubing. I'm able to sustain long tones with a tuner at 5 different pitches and questioning whether this is enough indication for me to buy a starter horn. If so, are there any recommendations for a purchase within a couple thousand dollars that would best support my goal? I'm also unaware of the qualities that vary among horns. For example: What is a compensating horn? ...compensators?
