Practice was envisioned to solve a problem I encountered while I was a musician. Since I was a part of many different musical groups, I had lots of different pieces to learn and perform. However, I would learn the majority of each piece without a problem, while the real challenges were usually much smaller sections: a few measures of a solo line, a few tricky transitions, or faster licks. I would spend the majority of my time practicing these
sections, rather than the entire piece top to bottom. I would bring all of my sheet music everywhere with me where I might have a few minutes to look it over and run it through: school, different rehearsals, and car rides. All I really needed was access to a few different sections of each piece. Practice allows musicians to build a library of sections they need access to the most, and make them easily available in a mobile format.
