hi, I see here that you are lookign for concerts and not expenseive ones well I know of one place that you could check out. The Fort Bend Synphony Orchestra, this is there web site FBSO.org.
The tickets aren't that much and kids 12 and under are free. Their first concert is coming up in september. Once it gets close to that time. they will start to have info on the concerts. As a matter of fact the first concert is free!
And I know this because I am a member of the orchestra. if you go to the web site and look at the musicans you will find my name i play the double bass. As for the music leasons, from what I have seen you could do piano or even violin leasons. I want to put my boys in piano and so that they can get an intro to music and if they still want to play later on they will choose to play the piano or other instruments. I would hope one of them would choose the double bass lol!
but yeah check out the web site, rigth now they don't have a schedule set up yet but they will in the coming months.
Hope this helps some.
