This fun little Bach tune is a great study for your left hand. When most people think "Classical" they don't think improvisation. However, musicians used to improvise ornamentations and slight variations all the time! There's lots of great Classical and Baroque style licks in the switcher. Check them out after working through the tune. This song is sometimes played relaxed and not too fast. Other times, it's as upbeat as any Bluegrass tune. Take it at your own speed. Some of the tougher licks will be extremely challenging, or near impossible, when the song is played faster, so be aware of that.
