Notes-per-string views select the first matching scale tones on each string at or above the starting fret, within a 12-fret window. These are position studies: crossing strings can repeat or skip pitches. They are not guaranteed continuous ascending runs or finger assignments. Four-note layouts can require stretches or position shifts.
