# Slap & pop

Thumb slap + popped strings — bass-specific articulation for funk and selective metal aggression.

## Slap and pop lab

Two cells at a slow tempo, printed as TAB with the count above. The thumb note is G on the E string at
fret 3 (G1); the popped note is the open G string (G2), the same letter one octave up.

1. **Slap, then pop on the "and" of 2** — three events in a whole bar: thumb on 1, the octave popped on
   the "and" of 2, thumb again on 4. Everything else is silence.
2. **Octave bounce with ghosts** — the same skeleton plus ghosts on the "and" of 1 and 3 and a second
   pop on 4. The "and" of 4 stays empty so the bar can turn around.

This room's sample bank is a *fingered* electric bass, so there is no slap in it. The lab gives you the
right pitches at the right moments and none of the sound — use it for the rhythm of a slap line. The
timbre only ever comes from your hands.

## Thumb slap

Forearm rotation, small motion, rebound. Quarters on open E first.

## Pop

Snap D/G up to frets; fret firmly; control volume.

## Ghost slap

Muted slap for rhythm noise; optional metal filler.

## Combining

S on 1, P on & of 2, ghosts fill — say it, then play.

## Common faults

Windmill arm, flat pops, loud pops, no mute.

## Seeds

Original slap/ghost cells and octave slap/pop ideas.

## Where the thumb lands

The slap sound is the *string hitting the frets*, not the thumb hitting the string — you throw the string
down onto the fretboard so it rattles on the way back. Hence: play over the end of the neck rather than
near the bridge, use the side of the thumb along the bone at the base of the nail, drive it with forearm
rotation like turning a key, and rebound off the string. Test unplugged in a quiet room: one stroke
should give you a click and a pitch. A thud means you are hitting harder instead of throwing.

## The octave shapes, by string pair

Bass strings are a fourth apart, so the two pairs you will use share one shape: thumb on the E string
pops two frets up on the D string, and thumb on the A string pops two frets up on the G string (thumb at
fret 5, pop at fret 7, both times). E string to G string does *not* give an octave — those strings are a
tenth apart, so the octave sits three frets *lower* on the G string and only from fret 3 up. That is the
shape the lab uses, because it needs no left hand; it is not the shape you use in a song.

## Tone notes
Bright enough for pops; small rotation; fix mute before blaming strings.

## Selective metal use
Optional ghost-slap color; never obscure the kick.

## The left hand does half the groove

In a real slap line the left hand produces at least as many rhythmic events as the thumb, and most are
not notes. It makes the ghosts (resting flat so the thumb strike gives a pitchless tick), it stops the
pop on a chosen subdivision, and it plays hammered notes the right hand never touches. Count out loud
which events belong to which hand — if they all belong to the right hand, your line is about half as
dense as a slap groove usually is, and speed is the wrong fix.

## Coordination ladder
Slap → ghosts → sparse pops → denser pops → dialect switch with fingerstyle.

## Deeper fault fixes
Rebound hover; fret before pop; ghost instead of rushing.
