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.

Same Sa drone as other rooms — practice bar below. Click frets on the neck for real electric-bass samples (credits); synth only if samples have not loaded yet.

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.
Pain in the forearm, wrist, or shoulder means stop. Rest, lower BPM, shorten sessions. Stamina is built in minutes per day, not heroic hours.

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

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)

  1. Open E / A / D / G — four even plucks each, i–m, with a click at 60.
  2. Root on E fret 3 (G), fifth on A fret 5 — whole notes, then halves.
  3. Add left-hand mute so idle strings stay dead.
  4. Same root–fifth as eighths; still every attack lands on the grid.
  5. Graduate to ghosts and gallop cells.

4-week starter plan

  1. Week 1 — Tune daily. Open-string fingerstyle. Root–fifth on E and A. Record 30 seconds.
  2. Week 2 — Muting + ghost notes. Simple 8th-note grooves with a click.
  3. Week 3 — Gallop seed patterns (Gallop). Stamina bursts of 90 seconds.
  4. Week 4 — One melodic line + natural harmonics (Lead bass).

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)

  1. Tune E A D G.
  2. Open-string i–m, one string at a time.
  3. Root–fifth whole notes on E/A.
  4. 10 seconds of total mute silence — prove the instrument can be quiet.
