Ready to become a legend? Music is complex. Sometimes you need to break it down and work on specific elements: tempo, rhythm, dynamics, intonation.
The Wheel allows you to ignore most of the rules of music. Give it a spin, and drill your trouble section by making everything insane! Run it once 'Super Slow' (but maintaining proper rhythm and intonation). Then try it with 'Extreme Vibrato or a 'One Whole-Step Sharp'.
Perfect to kill the pre-concert jitters, or pretend you are still educating your students the day before a break. Have fun! Go nuts!
