How can you tell if a child is musically gifted?

[geraldine1969]

P can find parts of songs and play them in tune on the piano and recorder by ear. Now 5 she has been able to do this since she was about 2.5 - 3. I play piano a bit (but was an adult learner i was certainly no prodigy!) but i have never really properly sat down and taught her. She is going to join a recorder group at school after half term and after a few casual sessions of playing around with a beginner book and cheap recorder this half term holiday she has picked it up really quick. Does anyone have a musically gifted child or am i being abit hopeful!!!
