This progressive scale system coordinates basic concepts from elementary to advanced scales in preparation for the Scale System by Carl Flesch. In some aspects it goes beyond the scope of the Flesch system. One-octave scales are introduced in patterns with emphasis on half steps and finger retention. The two-octave scale patterns are non-shifting. Three-octave scales are offered with traditional and modern fingerings. The double stop scales vary in fingerings in order to teach the basic concepts of double-stops. Harmonics are included beyond the scope of the Flesch system, in a basic form including natural harmonics.
