Lead bass
Treat the bass as a melodic and harmonic voice — not only roots. Focus: singing lines, chord stabs, natural harmonics, classical-flavored arpeggios, and expressive effects (wah, overdrive) used like a second guitar.
Melodic role
- Write a 4-bar phrase in A minor pentatonic on the G and D strings — leave space between phrases.
- Use slides into chord tones, vibrato on sustained notes, and wide position shifts.
- Trade: two bars of groove, two bars of lead fill — still lock with the kick on downbeats.
- Sing the line first; if you cannot sing it, simplify until you can.
Phrase shapes (original)
Call / response on one chord: low call on A/E, high answer on G/D.
G|----------5-7-5---- D|------5-7---------- A|--5-7-------------- E|-------------------| Am pent seed — invent rhythm
End phrases on chord tones (A, C, E for Am). Avoid parking forever on non-chord tones unless you resolve them.
Chords & double-stops
Power chords (root + fifth) and simple triads work on bass if you mute carefully. The strings are a fourth apart, so the fifth is two frets up on the next string — same fret would give you a fourth. Root on A, fifth on D, octave on G at that same fret: B and F♯ under a B octave. Play it as a roll or a block.
G|---4---- D|---4---- A|---2---- E|--------
Double-stop seed (root + fifth, then move):
G|-------- D|-2--3--4 A|-0--1--2 E|--------
Move shapes chromatically for a “lead harmony” drill (your own line — not a song quote).
Natural harmonics
Lightly touch above frets 5, 7, or 12 (do not press to the fretboard); pluck; lift the left finger. Chain harmonics into a short melody, then answer with fretted notes — see also Harmonics.
Expression & FX (concepts)
- Wah — sweep on sustained notes or slow phrases; park it mid-sweep for a nasal lead tone.
- Overdrive / distortion — clarifies pinched harmonics and chord stabs; keep the low E controlled with muting.
- Volume swells — classical / ambient colors between metal sections.
- Dynamics without pedals — soft flesh attack vs aggressive rest stroke on the same phrase.

Common faults
- Lead that fights the vocal — fill in gaps; do not stack dense lines on sung syllables.
- Losing the downbeat — every lead phrase should still “know” where beat 1 is.
- Muddy double-stops — idle strings ringing; mute like a rhythm guitarist.
- Wah noise — sweep only when a note is sounding; park the pedal between phrases.

G|------7---- D|----------- A|--7-------- E|-----------| same letter, two places
Slide into a chord tone:
G|----------- D|------5/7-- A|--5-------- E|-----------|
Practice ladder
- 2 bars groove / 2 bars rest — hear the space.
- 2 bars groove / 2 bars pent phrase ending on a chord tone.
- Add one double-stop stab on beat 1 of bar 5.
- Insert a 5–7–12 harmonic chime as a phrase ending.
- Record; check that kick-lock survived the fills.

What good sounds like
- Phrases breathe — silence is part of the lead.
- Chord tones feel like landings; tension notes resolve.
- Double-stops and harmonics are clear chimes, not accidents.
- When the groove returns, the pocket is immediately obvious again.

Double-stop lab
Hold root + fifth; roll low-to-high as sixteenths, then play as a block on beat 1. Mute everything else. Move the shape up chromatically four frets and back.
G|---4-4-4-4------ D|---2-2-2-2------ A|---2-2-2-2------ E|----------------| roll, then block
Groove / lead trade etude
Write (do not quote) an 8-bar form:
- Bars 1–2: pocket roots + ghosts.
- Bars 3–4: gallop cell on the root.
- Bars 5–6: Am pent lead phrase ending on A or E.
- Bars 7–8: harmonic chime + space.
Record once. Check that beat 1 of bar 1 and bar 5 still feel like home.
Session checklist
- Phrase sung before played?
- Chord-tone landing?
- Mute under double-stops?
- Pocket returns after the fill?
