How to count Boom-chick

Say the count out loud and strum only on the bold words: 1 & 2 & 3 & 4 &

↓ down · ↑ up · ✕ chuck (muted) · B bass note · b second bass note · bold: accent · dashed: palm-muted · underlined: short. The last row is the strumming hand, which keeps moving even where nothing sounds.

B D B D uses four of the eight eighth-note slots in the bar: all of them down strokes, with the hand swinging past the strings four times. Every stroke lands on a beat, so it is as steady as rhythm gets. The bar ends with a silent swing on the “&” of 4, a free moment to move your fretting hand to the next chord.

Playing it

For the “boom”, pick the root on the lowest string of the chord: the 6th string for G and E, the 5th for C, A and B7, the 4th for D. On the second boom, move to another bass string of the same chord.

Silent swings

On every “&” the hand moves without touching the strings. Keep it moving there, in the same down-up rhythm.

All down strokes

Lift the hand just clear of the strings between strokes. Keep that return small: at 100 BPM each eighth note lasts 300 ms.

Bass notes

On beat 1, pick only the chord’s root on its lowest string: the 6th string for G, the 5th for C, the 4th for D. On beat 3, pick another bass note of the same chord, a string or two higher.

Practise it step by step

  1. Bass notes alone first, on G; then add the strums between them.
  2. Hold G, set slow motion to ×0.5 (50 BPM) and play along until four bars in a row are even.
  3. Loop the trickiest moment on its own: the change from the down to the second bass note on beat 3.
  4. Normal speed at 60 BPM, with the click on if you want the beat under you.
  5. Chord changes: G – C – D, one a bar (or every 2 bars until the changes are clean).
  6. Up 4 BPM at a time to 100 BPM, then toward 130 BPM for faster songs.

At 100 BPM a bar lasts 2.40 seconds and you play 100 strokes a minute. Slow motion at ×0.5 brings that down to 50.

Chords to try

Folk and country strumming splits the chord in two: a bass note picked on its own, then a strum of the higher strings. Alternating between two bass notes makes the bass line walk, the sound of country, bluegrass and campfire songs.

One step away

  • Make the second bass note on beat 3 a bass note and you have Bass and strum (B D B D).
  • Add an up on the “&” of 4 and you have Boom-chick with a pickup (B D B DU).
  • Make the bass note on beat 1 a down, and make the second bass note on beat 3 a down and you have Four downs (D D D D).
  • Add an up on the “&” of 2, and add an up on the “&” of 4 and you have Boom-chicka (B DU B DU).
  • Accent the bass note on beat 1, and accent the second bass note on beat 3 and you have Boom-chick, strong bass (B D B D).
