Feel free to expand Bic, Vivaldi, Tchaikovskey, Wagner, Bach, Rachmaninoff, Bach, Chopin, Mozart, more should listen to the greatest composers that actually heard the music of an entire orchestra in their heads first.
Think about that folks, strings, which were at many levels, horns, percussion, controlling an orchestra, and writing the individual parts for each in sheet music, and than making it happen.
The entire symphony was in their heads. Quite a difference than the dribble of today. A lost art only known by a very few today.
Sorry, grew up with a classical pianist Mother, and I believe a Nazi escapee who migrated to S. Florida to teach Piano.
One of my favorite bits. They are called Masters for a reason, but hey,... now we have Justin Beiber....

Thanks Bic.
