What ever your favorite key[/u] is move your fingers up a 1/2 step & learn the next key til yopu learn all 12 keys their all your keys. I remember sitting on the organ when I first started & could'nt play a simple song like "Say Yes because I had not practiced in all the keys. Transposing only hurts you in the long run. Practice E, D, C, B, A, & the other keys we dont sing in on Sunday unless the song modulates then goes higher
