Joseph Alexander is one of the world's most prolific and respected music education authors and publishers. As the founder of Fundamental Changes, he has transformed how musicians learn, offering clear, structured, and accessible books that have sold over two million copies worldwide. His work spans genres and instruments, but his focus has always been on helping players bridge the gap between theory and practical application.A lifelong guitarist and educator, Joseph began writing instructional material after years of teaching privately and encountering the same frustrations among students: confusing theory, disconnected exercises, and a lack of musical context. Their clarity and effectiveness quickly gained attention. Within a few years, Fundamental Changes had grown into a global platform, with a catalogue covering everything from blues and jazz to metal and classical guitar.
