I think I remember hearing that when his #6 symphony was first performed he conducted the orchestra despite the fact that he was deaf at the time and the performance was so well received that the audience demanded an encore. It is mazing. Music, which is an art of sound yet a man who could barely perceive sound could compose and conduct it to such perfection.
I'll keep you posted as to the progress of our orchestra. Occasionally I post some of our upcoming and past events and recordings on the "art" forum of this Island. If we do the 9th I can't guarantee a full chorus although we do get a pretty good volunteer chorus when we do our traditional Handel Messiah concert. :)
Nice video. And while it doesn't show the notes, as per written on sheet music, it does show the notes in terms of the various instruments, range, note duration, chorus,dynamics, etc. And, at other times it reminds me of a NYC subway map.. :)
