My parents (who have both never played an instrument in their lives) signed me up for piano lessons when I was a child. I'd regularly be sent home with homework that I didn't know how to complete, no one taught me how to practice, and I'd frequently show up to lessons without any idea of what I was doing. I'm sure my parents paid a hefty fee, but I got zero value out of the experience. As an adult, I revisited the piano, and learned more by myself over several weeks than I ever did going to lessons as a child. The experience taught me how to practice better, and it gave me a stronger intuition for how the brain learns. The mistake my parents made was thinking that all the learning happens at the music lesson. That simply attending classes was enough to make me a better musician and a smarter child. I wonder how many other parents out there are making that same mistake right now.
