“My first experience with the guitar was taking lessons from Karl Aranjo as a high school student. His lessons were more than just a collection of tips and riffs: they were a method. As I look through, I get to take a trip back through those lessons and am reminded about I loved about them. His strong focus on the fundamentals quickly draws a connection between general music theory and the particulars of how that theory can be applied to the guitar, even allowing us as guitarists to use our instrument as an abacus-like tool to enhance our musical insight. In high school, Karl’s lessons got me up to speed to jam with my friends and in the school band almost immediately. In the almost 20 years since I left high school and had my last lesson with Karl, the things he taught me have continued to serve me well; I’ve played almost continuously in a variety of styles (jazz, rock, funk, folk), both as a hobby and as a part-time professional (currently playing with San Francisco’s Smash-Up Derby). If I hadn’t grown up in the same town as where Karl taught, I might have missed out on a lifetime of fun playing the guitar. With, wherever you are, you can benefit from the same quality instruction that I had!

“Mr. Karl Aranjo is one great teacher to work with. When working with him, he is very flexible, and will teach you all the basics and fundamentals you will need while learning how to play the guitar. From learning basic chords to crazy licks and solo’s. You will become an expert in no time and looking like a professional guitar player. In my experience, I learned to master chord progressions much easier and understand it in a better perspective. In my music career/hobby, it has given me nothing but success to play in a band as a front man/rhythm guitarist, compose my own type of music, and as well as songs that I really wanted to learn how to play on the guitar. Learning through Karl Aranjo was a great experience and has helped me understand the guitar a lot easier, I would not have wanted this learning experience any other way.”

-Julius Isaac

“I had the pleasure of being a guitar student of Karl’s for several years. Karl advanced my playing ability a great deal very quickly by giving me a perfect combination of guitar technique, theory and assigning songs that motivated me to continue learning. I highly recommend Karl for all level of guitar players no matter if you are a beginner or advanced.”

-Tom Hunt

Blake Aaron- Internationally Known Recording Artist

”Karl helped me dive into the blues when I was first starting out, and learning how to improvise opened up many doors for me on guitar. He has a vast knowledge ranging many musical styles, and i would recommend him to anyone trying to learn the instrument!”
