This document discusses how building guitars can be used to teach STEM concepts in an engaging way. It provides examples of how guitars have been integrated into classrooms and programs at various levels, from using guitars as examples for physics and math lessons, to having students fully design and manufacture guitars. Building guitars allows students to learn science, technology, engineering, and math concepts through hands-on projects, while engaging their interest in music. Resources and training opportunities are provided for educators to learn how to incorporate guitar building into their own STEM curriculum.
