I started on a full double. For a while I didn't know all the Bb fingerings on where I used the F side, or the F fingerings where I normally used the Bb side.
A few years ago I decided to learn them all, and I can tell you it sure does help. Yes it does sound differently on the Bb side but if you have some fast arpeggios or runs through partials from a low F below middle C to around the C in the treble staff and if they occur fast enough I always employ the Bb side because it's cleaner. You'd be amazed at the difference the Bb side can make in regions you don't normally use it. Of course this isn't to say one should neglect the F side. In fact I only employ the Bb side in regions I normally don't use it in times that it is more advantageous. I mean if one plays on a double (or triple) horn, one should know every bit of the range and fingerings for both (or all three) horns. One should also be familiar with each partial, where they are, and even alternate fingerings and their pitch tendencies. -William _______________________________________________ post: [EMAIL PROTECTED] set your options at http://music.memphis.edu/mailman/options/horn/archive%40jab.org
