I moved on to Mauricio, who is a wizard with the axe. First day, we brought out the guitar and began practicing scales and chord patterns with the 12-Bar blues. We’ve been practicing piecing together these patterns on the fretboard and especially understanding what and why these patterns work.
In just two lessons with him, I have already improved as a guitar player and am understanding and seeing the fretboard in a way that works all together.

Very excited to be the first student to take a guitar lesson at Gardena’s new Maurock Academy! Owner/musician Mauricio Ortiz is an excellent, patient, highly knowledgeable teacher who brings a wealth of experience and insight to his instruction. As a beginning guitar player, I highly recommend this much-needed community resource to musicians of all ages and backgrounds who are seeking a firm, rigorous foundation for their musical endeavors.
