Acoustic Guitar
## Core Behavior
- Create `~/acoustic-guitar/` as workspace on first interaction
- After practice, offer to log progress; see `progress.md`
## Before Advising
- Ask style — fingerpicking vs strumming vs both
- Ask genre — folk vs classical vs singer-songwriter
- Ask goals — accompaniment vs solo instrumental
## Practice Errors
- Strumming from elbow — wrist drives, arm follows
- Neglecting dynamics — acoustic demands expression
- Avoiding fingerpicking — essential for solo
- Ignoring nail care — nails affect tone
## Left Hand Traps
- Thumb over on barre — classical position for clarity
- Pressing too hard — minimum pressure
- Ignoring open strings — acoustic loves ringing
## Right Hand Traps
- All thumb on bass — fingers need independence
- Inconsistent attack — angle/nail changes tone
- Same strum pattern — vary per song
## Mistakes by Level
**Beginners:** Choppy changes, muted strings, no dynamics
**Intermediate:** Same pattern always, weak fingerpicking, no bass
**Advanced:** Style rut, ignoring tunings, capo dependence
## Fingerpicking Patterns
| Pattern | Style |
|---------|-------|
| Travis picking | Folk, country |
| Arpeggios | Classical, ballads |
| Hybrid picking | Pick + fingers |
Thumb independence first, then add fingers.
## Strumming Essentials
- Down-up foundation — accents change feel
- Palm muting — percussive texture
- Ghost strums — hand moving, miss strings
- Dynamics in wrist — relax soft, snap accent
## Troubleshooting
- "Chords don't ring" → fingers touching neighbors
- "Strumming dead" → wrist not elbow, loosen grip
- "Fingerpicking uneven" → thumb+one finger pairs
- "Barre muddy" → roll finger, bone edge
## Care & Progress
Humidity 45-55% — cracks without it. Log to `~/acoustic-guitar/`: songs, patterns
## What to Surface
- "Travis solid? Try Chet Atkins?" / "Strum done — fingerpicking?"
