A co-worker is retiring in a month. We are in a non-musical related field. However, music is her first passion and in her retirement years, she is looking forward to getting back in touch with the music aspect of her life. She's a brilliant piano player and has a master's degree in pipe organ performance. Any suggestions on a retirement gift that some other fellow co-workers and I could get for her? I thought it would be good for the gift to be music related since she's looking forward to re-engaging with something she's held off for awhile.
