Murphy Method Improvising - The First Stage DVD. Is a way of teaching bluegrass by ear. We use no tablature in our teaching because we believe that tablature is a crutch that interferes with learning to play bluegrass. Each song is explained note-by-note, so that it is easy & quick to learn. As you learn these tunes, you are also developing your ear. so that the learning actually gets easier as you go along!. Learning by ear is the first step in learning to play with other people.
