I've started many online jazz guitar courses but Peter Sprague's is a bit different. Being the seasoned performer he is and the collaborations he had with top jazz musicians he talks from the perspective of a professional guitar player who knows how to deliver the knowledge to a student. His jazz guitar course starts from the very beginning (pay attention though, it's not for absolute beginners, you must know your basic chords and scales to dive into it) explaining the major scale and the main chords with inversions. I've watched the first three lesson and I have food for thought and practice for six months! This is the premise for a great learning experience. I forgot: his insights on left hand technique for arpeggios is an eye opener. Not for every body but it works for me. You also get Peter Sprague's technique book as a free download, whose pages are often referenced to during the videos. Greetings from Italy.
