Right-Hand Scale Fingerings & String Crossing Exercises
A published printing from 1980 by Christopher Berg (www.christopherberg.com)
The scale exercises listed below are from an article by Christopher Berg from a publication in 1980 titled "Guitar Master Class: Technical Exercises by Famous Guitarists" that presents not only the popular a-m-i right hand pattern, but utilizes all of the right hand combination possibilities available to guitarists. This will aid guitarists in developing a well-rounded right hand technique for scale playing and applying valuable string-crossing exercises to these patterns to adequately perform various technical/musical situations in the extant repertoire of the classical guitar.
It is important to note that since the time of the publication, Christopher Berg recommends adding the right-hand finger combination i-a to the list of finger combinations. All of the right-hand finger combinations for scale playing can also be found in his current technique book Mastering Guitar Technique: Process & Essence by Mel Bay Publications in Lesson 23.
