Guitar Scale Fingering
Map any scale onto the guitar fretboard by position: fingers 1-4, root markers, and the positions that cover the whole scale — for classical and any six-string guitar.
Result
Guitarists learn scales as positions: the index finger anchors a fret, each finger owns the next fret, and the scale falls under the hand as a repeatable box. The same C major scale lives in several overlapping positions along the neck.
This tool draws the whole neck up to the 12th fret, shades the chosen position window, and numbers every scale note inside it: 1 is the index finger, 4 the little finger, 0 an open string. Notes outside the window stay as small ghost dots so you can see how the boxes connect.
Positions marked with a check contain every note of the scale within the four-fret window — those are the patterns worth memorizing first. The default position is picked so the root sits under your hand on the sixth or fifth string.
Labels switch between fingers, note names, and scale degrees, which makes the chart work both as a practice map and as a fretboard-theory reference. Everything runs locally in the browser in standard tuning.
