I have been playing the Soprano recorder for some time now, and also the Alto for a while as well.
The thing is, I never bothered learning the correct fingering for the Alto. That is, the fingering is the same, but only a 5th down.
So whenever I sight read music for the alto, I'm playing in a different key that it was written in.
I realize many instrumentalists do this by tradition, but I would actually like to be able to play in the correct key.
My concern is if I start playing the concert pitch and learn the correct fingerings by heart, is this going to affect my playing the soprano? Will I get confused, and occasionally play a G instead of a C for example? On the other hand I could simply arrange the score and read from the transcribed music, but that seems too complex and expensive...
What do other musicians do who play a transposing instrument?
What do the Pedagogues say about this?
