Greetings, I have been watching a number of solo euphonium + brass band/concert band type music. For most of my life I was convinced that there was no more beautiful brass sound than a (French) Horn in the hands of a real master. Obviously I am rethinking that since I am now spending so much time here amongst all of you. Anyway, what I have noticed is that some players have the instrument almost at a 90 degree angle to their body. The bell is pointed towards the audience. Is this done to aid 'projection'? Does it require any modification of the leadpipe? Does it have any positive or negative impact on the arms and/or shoulders? In other words, could this be a 'better' position for playing euph. than the usual one with the instrument parallel to your body?
