Hi
I am a musician and former music teacher. I taught middle school band for 13 years before I was diagnosed with NF2. I had just finshed a Master's in music 4 months before I was diagnosed. I am deaf in one ear and have normal hearing in the other at this point. I taught band for one year after becoming deaf on one side. It was very frustrating. Although I could still hear a wrong note, I couldn't locate the source and see the student using an incorrect fingering. It changed the way I rehearsed the band, and drove me nuts! Since I knew that I would at some point be unable to teach band, and since an opportunity to move into a different postition, that was my last year teaching band
I put my trumpet away after I finshed teaching band. I started grad school and haven't had time to play. I did continue to sing in various groups, and found that where I stood in relation to the group was critial to how comfortable I felt. It just takes adjusting. My sister has SSD (not related to NF2) and she is a fabulous flute player and singer. However, she grew up with SSD and learned to sing and play with SSD, so she doesn't know anything different. I think that it's just a matter of learning to listen differently. You may have to work a little harder on intonation, but it can be done.
I hope this helps,
Jeff
