AMF Semester 1: Acoustic Guitar Track

Instrument Interface for The 12-Bar Laboratory

Version 1.1 | Incorporates audit refinements from Layer 11

---

Guitar Track Purpose and Scope

This document adapts the shared Semester 1 Core Curriculum to acoustic guitar. It is not a separate guitar course. It is the guitar interface for the same AMF semester — the same monthly arcs, the same anchor songs, the same Internal Band systems, applied through the physical and sonic vocabulary of the acoustic guitar.

Primary guitar role in Semester 1: Acoustic support, groove, triad mobility, fingerstyle foundation, fills and short answers, and simple arrangement thinking.

Right-hand assumption: Fingerstyle-friendly (thumb and fingers, no pick required). Strumming is trained through fingers, thumb, nail, and muted strokes rather than pick-dependence. If you use a pick, adapt accordingly — the musical goals are identical.

What the guitar track does not pursue in Semester 1:

• Full advanced chord-melody arrangements
• All CAGED positions in all keys
• Fast lead playing
• Complex Travis-picking or full thumb/finger independence
• Advanced walking bass with chord independence
• Deep 013 PCS exploration
• Genre surveys as separate courses

Every drill must serve a musical AMF function. Technique is not allowed to become a separate sport.

Guitar Setup and Instrument Check

Before Month 1 begins, complete this setup once:

Tuning: Standard EADGBE. If the guitar is difficult to hold in tune, have it professionally set up. Poor tuning stability during practice trains the ear incorrectly.

Action and setup: If fretting single notes requires excessive force or creates buzzing, the guitar may need a nut or saddle adjustment. You cannot learn relaxed technique on an instrument that fights you.

Practice space: You need a space where recording is possible. A phone propped on a book is sufficient. The key is that setup should take under 30 seconds, or you will not record consistently.

Primary key for Month 1: E major blues or A major blues. Both are open-position friendly with standard guitar tuning. A minor blues enters in Month 3. If you need to play with a backing track in a different key, use a capo — the shapes remain the same.

The Six Core Guitar Drills

These six drills are the technical spine of Semester 1. They are deliberately few. Each drill should feel like a doorway into many musical uses, not a disconnected exercise.

Drill 1: Tension Check and Relaxed Chromatic Control

Purpose: Prepare the hands, remove excess pressure, and build clean acoustic articulation.

Steps:

1. Start with the guitar silent. Notice shoulders, jaw, wrist, thumb pressure, and breathing.
2. Fret one note with only the pressure needed for a clean tone — not more.
3. Play a slow four-finger pattern on one string, then across two strings.
4. Keep unused fingers close but relaxed.
5. Stop before fatigue becomes tension.

Standard: The drill is successful when the hand feels more organized after two minutes, not more tired. Do not chase speed. Use this as a calibration ritual at the start of every session.

Drill 2: Muted Pulse and Groove Engine

Purpose: Make rhythm feel good before harmony enters.

Steps:

1. Mute the strings with the fretting hand.
2. Play quarter-note pulse, then eighth-note 2-cell, then triplet-shuffle 3-cell.
3. Accent different parts of the cell — feel what moves.
4. Move between downbeat and upbeat entry.
5. Only after the groove feels stable, add one chord.

Standard: The muted version should sound musical by itself. If adding a chord weakens your time, return to muted strings. Time first; harmony second.

Drill 3: Bass and Chord Fingerstyle Pattern

Purpose: Build acoustic accompaniment through thumb/finger role separation.

Steps:

1. Choose one chord.
2. Thumb plays the bass note only.
3. Add a light chord or pinch after the bass.
4. Practice bass → chord as the entire pattern.
5. Add an inner or top note only when the groove stays stable.

Standard: One simple pattern used in a real form is worth more than ten memorized patterns. Use this drill for blues, folk, gospel, R&B, and solo acoustic settings.

Drill 4: Triad Map and Arpeggio

Purpose: Turn TPS into playable guitar material.

Steps:

1. Choose one small triad shape (three strings, not full barre chord).
2. Play it as a chord grip.
3. Play it as an arpeggio — one note at a time.
4. Move it to a second inversion or different register.
5. Use two or three notes from it as a fill.

Standard: The same shape should function as support, color, arpeggio, and melody in different contexts. Do not map the entire neck before using one shape musically.

Drill 5: Call-and-Response Fill

Purpose: Develop musical speech and restraint.

Steps:

1. Play one simple chord or groove as the call.
2. Answer with two to four notes.
3. Leave at least one full beat of silence.
4. Repeat the fill with changed rhythm.
5. Record and ask: did the fill improve the music?

Standard: A fill is not successful because it is technically impressive. It is successful if the music sounds more alive after it.

Drill 6: Long-Time Form Pass

Purpose: Build 2-bar, 4-bar, and 12-bar form awareness as felt experience.

Steps:

1. Play only on bar 1 and bar 3 of each four-bar phrase.
2. Then play one chord per bar through 12 bars.
3. Then play your actual texture while still feeling the larger four-bar anchors.
4. Do not count excessively — learn to feel the form.
5. Record and observe whether the form breathes.

Standard: The 12-bar form should eventually feel like a room you are walking through, not a math problem you are solving.

Guitar as Secondary Instrument

If piano is your primary instrument, the guitar track functions as a visualization and exploration tool in Month 1. This means:

• One guitar session per week rather than five
• Simpler versions: muted pulse only, or single-string arpeggios rather than full chord textures
• No pressure to match piano execution quality
• Use the guitar to visualize the AMF systems physically — movable shapes make TPS visible in a way that complements piano's harmonic clarity

Month 2 is when the secondary guitar track deepens. By then, your primary instrument is stable enough that you can invest more practice bandwidth in the second interface.
