I like to introduce Christmas carols into my cornet practice sessions in October. By Thanksgiving I have them down. I like to go up on Main Street and play, especially when it's snowing. Last year, I walked up to the Kettle bell ringers and started playing. What fun!
At least an hour a day for music. Either playing or listening. That's an order!
I used to start practice of carols way before Christmas. Played at church Christmas Eve for a few years, and Christmas Day for my family. I lost the desire to play anytime of year. My beautiful piano waits for me.
