Hi there..  I'm rather new to all this having only recently developed
an appreciation for "classical" music.  However, in my travails through
various pieces by Messr's Bach, Handel, and Vivaldi, I have noticed that
while most major keys seem well represented, there seems to be very
little use of B Major as the tonic.  Is this unique to only the baroque
period or (as I suspect) the entire "classical" milieu, and why?

Thanks;
John
