Music Lessons

At what age should a child start muisc lessons?

Since I have no talent for music, I wanted an answer when I discovered my child could keep time.

I found a site which has helped me understand age and music. Go to: http://musiced.about.com/od/beginnersguide/a/atwhatage.htm for additional information.

I found a child size violin 1/4 at www.gotoerins.com . I bought one for my daughter and the guitar for my son. They are twins.
