Last weekend I was subbing in a big band on second tenor and we played ‘In the Mood’ by Glenn Miller.

The main melodic line has a harmony on that part that goes from G to Bb to F.

Using the side Bb fingering is pain for that!

But, as I figured out/remembered towards the end of the song, it’s much easier to use the ‘F’ fingering for Bb in that situation.

You play a B like normal in the left hand and also include your pointer finger down for your right hand.

This makes going from a G to a Bb to an F really easy!

There are several fingerings for Bb.
