This Innovation Grant allowed Kepler School to expand the Guitar Building Woodshop. By doing so, more students had an opportunity to build a Cuban drum known as a cajon, or a cigar box electric or bass guitar. Working alongside a professional guitar building craftsmen, students learned how to compose and perform music on these instruments for monthly Kepler Art Hop events. Students learned familiarity with hand tools and wood working while building their own instrument entirely from scratch using raw materials. Students applied math skills for measurement, and art and technology skills for beautification and design. They also learned how to compose and perform an original composition that will be captured in a video or audio recording.
