I have been playing as a comeback player for a few years now and find that even in a concert band I usually choke when asked to step out of my sectional role and attempt a solo. I usually spend my working day standing in front of a classroom full of strangers and teach technical subjects to very experienced engineers, and have done for 25 years - so shyness would not seem to be a factor. What is going on? Very recently I read David Monette's dissertation on body centring and tried it at band last night whilst attempting a solo - concentrate on feet position, knee position, hip position, weight over the middle of the feet - solo proceeded just as it does in the practice room - almost perfectly (within the limits of my skill level). Any thoughts?
