Well I can only play by ear, I know which dot is which if I spend some time looking but I find if I want to play a tune then I only have to listen to it a couple of times and I can usually do it. The chords I rarely have a problem with as I can usually recognise which chord to play and when.
Of course that restricts one a little - when I used to back artists at a club they would give me a sheet of music and rightly expect me to play it. The club then restricted the artists to those who didn't need me to do this. The key didn't matter as I just transposed the organ and always played in C.
There again when I played bass guitar in a trio the pianist although a fantastic player was just a reader and could play any classical piece put in front of him but if he had to play Happy Birthday then he used to get up and let me play it because he didn't have the dots.
I'm happy to be able to only play by ear but I suppose underneath I would really like to have learned to read music and I admire anyone who does.
As Gordon says it must be great to be able to do both
