Pick a root and a scale, and watch the notes fill the whole fretboard — no more being stuck in first position.

C Minor pentatonic · The first position for rock / improv — learn this one first
Red = root, orange = scale notes; open-string notes sit to the left of the nut (the thick line on the far left). Tap any note to hear it, or press "Play scale" to hear one octave ascending from the root. Switch the labels to "Degree" to see the relative intervals; change the root or scale and you'll see the same position shape slide as one along the fretboard — that's the heart of the five scale positions.
