This is from my new book Classical Guitar Technique: Essential Exercises, Scales, and Arpeggios. The 122 page book includes: Practice Routines, Tips, 100 Open String Exercises, 120 Giuliani Arpeggios, Scales, Slur Exercises, Shifts, Finger Independence, Barre, Tremolo, Common Harmonics, and much more.
The following one octave major scale patterns are useful for gaining control over synchronization of the hands, general precision, and coordination. They are also useful for recognizing octave patterns in scales. Certain keys are used below as examples but practice the patterns in various keys by playing the same pattern/fingering at different frets. I’ve started each scale around the 4th and 5th position for left hand ease.
