Most of us remember how tricky it was to learn to ride a bicycle. Falling down, scraping our knees, running into trees, or even the neighbor’s carefully trimmed hedges. Or maybe that memory is too far in the past for you, but you do remember teaching your son or daughter how to ride a bicycle. After privately chuckling to yourself the first few times they wobble and stutter, you probably encouraged them to try again. And if they were still having a really hard time, you probably suggested, “Let’s install some training wheels for you.” Sometimes a little extra help from training wheels makes things a lot easier. Similarly, it makes sense to use “training wheels” to help us learn to play an instrument, something that’s arguably far more difficult than learning to ride a bike.
