3NPS stands for “3 Notes Per String” — three notes per string. Instead of playing a scale in just one small region of the fretboard (like the classic pentatonic boxes), the scale spreads across all six strings with three notes each — and moves on from there in consistent steps across the entire fretboard.
Why it’s useful
- The fingering is built the same way on every string — easy to remember.
- You automatically learn to think across the whole fretboard, not just one box.
- Ideal for fast, even runs with alternate picking.
Seven positions
A major or minor scale has seven degrees — and accordingly seven 3NPS positions, one per starting note.
To practice: get one position solid first, with a metronome, starting slowly. Only move on to the next once it sits — don’t learn all seven at once.
