3 1/2 isn't too young to benefit from some training, especially if the teacher has experience with younger children. Check with your local music stores for some advice of teachers who have this experience.

She is now two & a half, she is starting to sing some songs that her toys sing. I don't know the age for formal training being started but it doesn't seem any time is too early for getting them interested in music. dkm.st

Prior to that, I did programs like Kindermusik when my kids were as younng as a few months old. It's great bonding time and it helped to teach me new ways to include music in my children's day (I am not a musician, my kids usually ask me to STOP SINGING!)
