The system of major/minor scales with the ½ tone pitch, which I offer here for studying and practicing has three levels of difficulty:
1) 2 octave scales for beginners,
2) 2 ½ octave scales for the medium level viola players,
3) 3 octave scales for advanced viola players.
From my experience I know that in many cases 2-octave scales are too easy for a student when 3-octave ones are still too difficult. Too wide gap between 2- and 3-octave scales is filled here with the 2nd level of difficulty, namely, 2 ½ octave scales and arpeggios.
