She still performs with Steve for various occasions. They raised two musical sons, Peder and John, and Patti remembers, “In our family it all started with singing and listening to good music. That was the easy part, the mother tongue method. The difficult part was setting aside enough time to be patient and feel creative with our home practice. I know it’s not easy. But watching other parents through the years, I see evidence that with persistence and love, much can be accomplished!”
