5-6 · Horizontal navigation with 3NPS

The seven-string pattern from the last lesson covers vertical movement, but in my opinion, horizontal movement and melodic sequences are where 3NPS really earns its keep. That's what this lesson and the next are about.

One string

Back in 2-3 we walked the scale up a single string one fragment at a time — Fragment 1, then 2, then 3, and so on. That still works. But the 7-3-6-2-5-1-4 sequence gives us bigger jumps: the same sequence that tells you which fragment sits on the next string also tells you which fragment starts three scale degrees higher on the same string. Play Fragment 1, shift up the string, and Fragment 4 is waiting. After 4 comes 7. In reverse, each step backward through the sequence drops you three scale degrees: from Fragment 1, shift down to 5, then 2.

The only trick is knowing whether there's an empty fret between neighboring fragments on the string. The major scale's two half steps sit between degrees 3–4 and 7–1, so a fragment that ends on a 3 or a 7 runs straight into the next one.

Memorize this: Moving up one string through the 7-3-6-2-5-1-4 sequence, there is an empty fret after every fragment except Fragments 1 and 5.

Pivoting between vertical and horizontal

Here's what makes this more than a party trick. One mental model now covers both directions of movement, so you can switch between them any time you want, even mid-phrase, without changing systems. The anchor is always the same: the scale degree under your index finger.

In the video, I played up the F major scale three notes at a time, switching between vertical and horizontal movement along the way. The 7-3-6-2-5-1-4 sequence continues unbroken through every pivot, and it sounds like one continuous scale:

I'm not suggesting this is easy at first. But it isn't hard to understand, and with practice the switching becomes smooth. This is the real reason we spent so much time on the vertical pattern: once it's in your fingers, every position on the fretboard becomes a potential pivot point.

Two-string Pairs

Slicing the seven-string pattern into two-string units yields seven shapes I call Pairs, each made of two adjacent fragments from the sequence. I name each Pair by the scale degree of its lowest note: Pair 1 has Fragment 1 on the bottom and Fragment 4 on top, Pair 2 has Fragment 2 under Fragment 5, and so on through Pair 7. There's nothing new to memorize here — if you know the sequence, you already know every Pair. You're just learning to see two strings of the pattern as a unit.

Pairs shift horizontally in the same way fragments do. Move your index finger to the second note of the lower fragment, and you've shifted up one scale degree — Pair 1 becomes Pair 2. Or jump three degrees at a time by following the sequence: Pair 1 to Pair 4 to Pair 7. Descending works the same way in reverse. The whole time, the only thing to track is the scale degree under your index finger on the lower string.

Melodic sequences are where the Pairs really shine. Six notes under your fingers is enough for real melodic material, and the payoff is that the picking or legato pattern for a given sequence is identical in every Pair, with fingerings close enough that muscle memory transfers. Get a figure under your fingers in one Pair, and you can transfer it anywhere on the neck:

We'll return to melodic sequences in a structured way in Module 6. For now, just notice how naturally they fall out of the Pair structure.

Exercise 5-5: Pick a mode and a string, and set up a drone. Walk the scale up and down the string using fragments, saying each fragment's number out loud. Practice shifting by one fragment at a time and by threes using the sequence, watching for the gaps.

Exercise 5-6: Pick a mode and a starting note, and practice moving in all four directions: next string up, next string down, toward the bridge, toward the nut. Deliberately pivot between vertical and horizontal a few times along the way, naming the scale degree under your index finger at each shift. Slow is fine — the point is seeing that the system keeps working through every pivot, and with a drone running, you'll hear it immediately when something's off.

Exercise 5-7: Pick a tonal center and a string pair, and run a simple melodic sequence horizontally up and down the neck through the Pairs. Then move to other string pairs. Budget extra time for the G-and-B pair, because of the warp.
