Foundations
Four thick strings, E A D G (one octave below the bottom four of a guitar). Shared harmony lives on Western theory — this room is pocket, tone, and bass-only craft.
Parts and hold
Bass: long scale (usually 34"), fretted or fretless, 4–6 strings. Sit or stand with the neck slightly up — the nut should sit near shoulder height so the fretting wrist stays relatively straight.
Fretting hand: thumb behind the neck (roughly opposite the middle finger), one finger per fret when possible (1–2–3–4 in a four-fret box). Keep the palm off the neck; only the thumb and fingertips contact wood/metal.
Plucking hand sits near the end of the neck or over the pickups. Most rock / metal bass here uses fingers (index + middle), not a pick — see Fingerstyle.
- Strap height — standing and sitting should feel similar. If standing feels like a different instrument, raise the strap.
- Neck angle — slight upward tilt reduces left-wrist bend on frets 1–5.
- Balance — the body should not dive; adjust strap buttons / strap locks if needed.
Setup & ergonomics (practice hygiene)
Pedagogy first: a painful setup teaches bad habits. You do not need a pro tech to start, but check:
- Action — strings high enough not to buzz, low enough that fretting does not fight you.
- Intonation — fretted 12th and harmonic 12th should agree; otherwise pitch lessons lie.
- String gauge — medium sets are fine for learning; ultra-light strings can feel “floppy” under gallop attack.
- Warm hands — 60 seconds of open-string i–m before anything fast.
Tuning — E A D G
From thickest (lowest) to thinnest (highest): E1 · A1 · D2 · G2.
- Shared tuner (bass · EADG) — or a clip-on.
- Same letter names as guitar’s bottom four, sounding an octave lower.
- Drop D and 5-string: Tunings.
Reference drill: tune open strings, then check fretted 5ths (E5 = A open, A5 = D open, D5 = G open). If fretted and open disagree, the instrument needs setup — do not “practice around” bad intonation.
Open strings — click to hear
Click each open string. Listen for even volume and a clean attack with no neighbor-string buzz. That is your baseline tone for every later drill.
Bass TAB
Four lines — G on top, then D, A, E at the bottom (highest pitch on top, same convention as guitar).
G|-------- D|-------- A|-------- E|---0---- → open E
Numbers are frets. 0 is open. Rhythm is often implied by spacing or written above the staff —
always prefer a click over guessing. More symbols: Reading & TAB.
G|---------------- D|---------------- A|--------2------- E|-0--0-0-----0---| original seed: root + gallop cell idea
Left-hand mechanics
Bass frets are wide. Do not stretch with a collapsed wrist.
- Fingertip pads — press just behind the fret wire, not in the middle of the fret space.
- One-finger-per-fret — default for scale boxes; pivot the thumb when shifting positions.
- Shift early — move the whole hand; do not leave pinky stranded three frets away.
- Mute neighbors — unused fingers lightly touch idle strings (see Muting).
Seed — chromatic box frets 1–4 on E, then A:
G|----------------- D|----------------- A|----------------- E|-1-2-3-4-1-2-3-4-| fingers 1 2 3 4
Right-hand overview
Two jobs: start the note (attack) and stop other strings (mute). Fingerstyle is the default engine for this room’s metal-oriented path; slap is a separate dialect.
- i / m alternation — never habitually double-tap the same finger at speed.
- Contact point — nearer the bridge = brighter / tighter; nearer the neck = rounder / fatter.
- Rest stroke option — pluck so the finger lands on the next string for punch.
- Thumb — anchor lightly on a pickup/string, or float for muting (both valid).
Deep dive: Fingerstyle.
What bass adds (beyond guitar / ukulele)
- Role — lock with the kick; root motion before fancy fills.
- Right hand — fingerstyle attack, floating/anchored thumb, slap & pop.
- Groove tools — ghost notes, muting, rakes, space.
- Metal dialects — gallop drive, lead-bass lines, open-string drones, and harmonics.
Guitar room still helps for scale theory and fretting discipline; ukulele for light finger independence. Neither replaces bass pocket or slap.
Deep dive: Bass vs 6-string guitar — job, physics, habits to drop, one-week drill.
Common faults (fix early)
- Buzzing frets — not enough pressure, or finger too far from the fret wire.
- Sympathetic ring — open strings ringing under fretted notes → left-hand mute missing.
- Timing floats — playing “with the song in your head” instead of a click.
- Death grip — squeezing the neck; tone gets choked and stamina dies.
- Looking only at fretting hand — right-hand alternation falls apart unnoticed.
Practice ladder (first month)
- Open E / A / D / G — four even plucks each, i–m, with a click at 60.
- Root on E fret 3 (G), fifth on A fret 5 — whole notes, then halves.
- Add left-hand mute so idle strings stay dead.
- Same root–fifth as eighths; still every attack lands on the grid.
- Graduate to ghosts and gallop cells.
4-week starter plan
What good sounds like
- Open strings speak with a clear attack and a controlled decay — not a wash of open-string noise.
- Root–fifth shapes feel “planted”: both notes same volume, no buzz, rest between phrases is true silence.
- You can sing the rhythm of your part while the click is on.
- After a short session your fretting hand feels warm, not locked or tingling.
Daily start (5 minutes)
- Tune E A D G.
- Open-string i–m, one string at a time.
- Root–fifth whole notes on E/A.
- 10 seconds of total mute silence — prove the instrument can be quiet.
