But, Jack, if those songs were transposed so the F recorder player could play them as if they were C fingerings, but they would play at treble pitch, the fingerings wouldn't change, just the dots on the page. Actually, there was a movement back in the 1950's or 60's to make one of the sets of recorder a transposing instrument so all recorder players could move easily from one range of instrument to another without those pesky fingering issues. I'm glad it went nowhere but, OTOH, if leeneia wants to do the work to help out a friend, I see no harm in it. I suspect as time goes on, he'll learn to play the F fingerings just as most recorder players do. I always liked the idea that recorders weren't transposing, because it gave me a much greater body of music from which to choose.
