The third movement of Bach's second Brandenburg Concerto calls for multiple trills on the middle G in F. The fingering is highly awkward because it is right between two registers and I am looking for an easier method to obtain the trill. I am aware of playing G with the left digits 2, 3, and 4 and the right digits 2, 3, 4, and 5, but trilling with my right fifth and fourth digits is just about as difficult as well. Is there any alternate method for the trill?
Kenneth Wollitz in his The Recorder Book suggests using the alternative G fingering you describe, and trilling on your right third finger. I just tried it, and it seems pretty reasonable.
