The 3-Notes-Per-String (3NPS) Scale System for Speed & Modal Fluency

Traditional position playing often alternates between 2 notes and 3 notes per string, creating uneven pick-stroke requirements when crossing strings.

The 3NPS system solves this problem by ensuring every string contains exactly 3 notes. This yields three massive mechanical advantages:

1. Strict Alternate Picking Consistency: Every string change alternates predictably between Down-Up-Down and Up-Down-Up strokes.
2. Standardized Fingerings: Only three finger combinations exist across the entire neck:
   • Pattern A (Whole - Whole): Fingers 1 - 2 - 4 (e.g., frets 5-7-9)
   • Pattern B (Half - Whole): Fingers 1 - 2 - 4 (e.g., frets 5-6-8)
   • Pattern C (Whole - Half): Fingers 1 - 3 - 4 (e.g., frets 5-7-8)
3. Direct Modal Visualization: The 7 distinct 3NPS patterns map 1:1 to the 7 diatonic modes (Ionian, Dorian, Phrygian, Lydian, Mixolydian, Aeolian, Locrian).

Starting on each degree of the major scale generates a unique modal mood:

• Pattern 1: Ionian (Major): Bright, resolved, triumphant (1 - 2 - 3 - 4 - 5 - 6 - 7).
• Pattern 2: Dorian: Jazzy, soulful minor with a natural 6th (1 - 2 - ♭ 3 - 4 - 5 - 6 - ♭ 7).
• Pattern 3: Phrygian: Exotic, dark Spanish/metal sound with a flat 2nd (1 - ♭ 2 - ♭ 3 - 4 - 5 - ♭ 6 - ♭ 7).
• Pattern 4: Lydian: Dreamy, futuristic sound with a sharp 4th (1 - 2 - 3 - ♯ 4 - 5 - 6 - 7).
• Pattern 5: Mixolydian: Classic rock and blues dominant scale (1 - 2 - 3 - 4 - 5 - 6 - ♭ 7).
• Pattern 6: Aeolian (Natural Minor): Emotional, sorrowful minor (1 - 2 - ♭ 3 - 4 - 5 - ♭ 6 - ♭ 7).
• Pattern 7: Locrian: Unstable, diminished tension (1 - ♭ 2 - ♭ 3 - 4 - ♭ 5 - ♭ 6 - ♭ 7).

When practicing 3NPS scales:

• Strict Alternate Picking: Maintain strict Down-Up-Down-Up picking regardless of string changes to build metronomic synchronization between both hands.
• Economy Picking (Sweep Picking transitions): Stroke Down-Up-Down on string 6, then sweep Down on string 5.
• Three-Note Legato: Pick only the first note of each string and execute two snappy hammer-ons or pull-offs for fluid, violin-like speed runs.

3NPS and the chord-first CAGED system are complementary: CAGED tells you what to target, 3NPS teaches you how to move across the strings at speed. Notate your first patterns using the symbols in How to Read Guitar Tablature & Notation.
