Throughout my pre-college scholastic career I was always involved in some sort of band or orchestra-related activity. In college I had to take an Intro to Music course to satisfy a prerequisite. There was a section of the course where the students had to identify a myriad of instruments. Having been surrounded by them for almost a decade, I had no problem breezing through this, but this app is dedicated to anyone who didn't have the exposure I did. I hope this helps you get through that section of your course. Good luck.
