I would like to find some music that all three of my kids can perform together for their grandparents at Thanksgiving and Christmas. After looking through the music store, I think that some of it I am going to have to come up with on my own. After searching old threads here and doing some intensive theory review last night, I think I was successful in transposing a version of the doxology from piano to trumpet last night. However, what happens when you transpose and you don't like the outcome? I think it now might be too high and have too many notes that my son does not know. Granted, he will likely learn them quickly as he has every other time he has attempted a new not, but I don't want to push him with a song that is too high. I am planning to pick up a hymnal at the used book store today and use the doxology from that. The online option I found last night didn't have a single chord in it but it was perfect for me to practice transposing with. I am trying to work out parts for a trumpet, piano and violin. The kids seem to really love it when they play together. We bought the suzuki piano accompaniment book that my oldest can play while the middle child plays the violin. But finding something for all three is providing to be a challenge. Keep in mind I have minimal musical training, just some basic piano as a child and the theory that went along with it. However, as a home schooling family, we strive to model for our children that you are never to old to learn something new. I am completely willing to work on learning more complicated musical theory if I need to in order to keep their musical training fun and something that they can at times do together.
