The 144 Day Practice Challenge is designed to advance your skill level and increase your arsenal of riffs which will result in more focused, deliberate, and pointed lines in addition to stronger improvisational ideas. When playing improv, it is all about your “bag of tricks” or a variety of riffs to draw from. If your bag is a little on the light side, you may end up running out of ideas halfway through a solo or early in the set. This book is a collection of warm-up exercises focusing on the Major, Minor, and Diminished Pentatonic scales which will quickly lead to an improved ability to navigate any situation at any time and in any key so you will never get backed into a corner or caught off guard. The 144 Day Practice Challenge puts a series of exercises for all twelve keys at your finger tips.
