Three-Notes-Per-String (3NPS): A Map for Fast Runs and Licks
Another scale system beyond the five positions: exactly three notes on every string. The fingering is tidy and easy to speed up — a powerful tool for licks, legato, and shred, and it ties the whole fretboard together once again.

What “three notes per string” means
Lay out the major scale as “exactly three notes on each string” — six strings, 18 notes total, with a wide span and fingering that repeats in a tidy way, especially suited to legato (hammer-on/pull-off runs) and fast alternate-picked lines. It's a complementary map to the “five positions” you learned earlier: the five positions are handier for fretting chords and shaping melodies; three-notes-per-string is better for playing fast and reaching far.
Seven shapes, named by their starting note
The major scale has seven notes, so there are seven shapes, each named for its starting note: the Fa, Sol, La, Ti, Do, Re, Mi shapes, pushed up in order toward the higher positions (in the key of C they roughly fall around frets 1 / 3 / 5 / 7 / 8 / 10 / 12). The seven shapes link end to end and pave the entire fretboard.
The neat part: each shape starts on a different note, which corresponds exactly to a mode (echoing the “intro to modes” lesson). So practicing three-notes-per-string means you brush up on the modes along the way.
- 💡 Master one shape thoroughly first (start with whichever is handiest for you), then link out to either side.
How to practice
First get one shape solid ascending and descending (with the metronome, either alternate picking or all legato); then practice connecting two adjacent shapes — shift positions by sliding across on one string. Always put “even and clean” ahead of “fast” — speed is a byproduct of accuracy.
⚠️ Common mistakes
- Lumping it in with the pentatonic / five positions — three-notes-per-string is another layout of the seven-note major scale, tidier and better for running fast.
- Sticking to just one shape — the seven shapes need to link end to end like the five positions before they count as connected.
Practice checklist
- Choose one three-notes-per-string shape and, with the metronome, get it solid ascending and descending with even articulation.
- Connect two adjacent shapes, extending one shape toward the higher position and one toward the lower.
