Boom-chuck
Sound summary
Folk is played with a bass-and-chord figure — 4/4, straight (even subdivisions) — for the guitar: the thumb plays the bass (B) and the chord (A) answers right after. To the ear: B A↓ B A↓.
How to count it
The meter is 4/4: 4 beats per bar, counted in one strum per beat. Say the beats: 1 2 3 4. Keep the beat with your foot and follow the grid: each box is one beat.
The rhythm grid
B = bass (thumb) · A = chord · ↓ down-stroke
The ↓/↑ direction follows the bowed-string arcada convention (ᴨ down, V up; Ribeiro 2017).
How to play it
Right hand
The strumming hand alternates two voices. The thumb (or the pick on the bass strings) plays the bass (B) and marks the pulse; the fingers (or a down-stroke) answer with the chord (A) right after.
Left hand
Keep the chord well pressed through the whole pattern — the left hand rules pitch, the right rules the bar. Only release the shape at the end of the bar, moving the hand ahead to the next one.
Example in C
Over a C chord, the bass (B) is the note C on the low string — the chord’s root. Play that bass on the pulse and let the whole C answer right after. Hear the example and follow the diagram.
Common mistakes
- Gluing bass and chord to the same instant. The B has to come first and the A answer — if they land together, the bass-chord bounce vanishes.
- Losing the pulse. The time has to stay firm start to finish — count along and don’t let the pattern speed up or drag by accident.
Guided practice
- Bass alone. Play only the B hits (thumb), very slowly, feeling each one land in time.
- Chord alone. Now play only the A hits, answering the bass, without the bass note.
- Put the hands together. Bass first, chord after — slowly, until the alternation is automatic.
- Close with the metronome. Go slow first and raise the BPM only once the pattern comes out clean.
You already get the logic of the groove. Putting it in time is where it enters your fingers: hear the pattern, follow the count and practice with a metronome — slow first — until the bass and the chord sit apart in time. That’s what Chord & Fret does, with guided audio and an adjustable tempo.

With the strum steady, take it to actual Folk progressions: rhythm, chord changes and voice-leading in one exercise. That’s the Progressions by Rhythm feature in Chord & Fret.
Train with progressions →Understanding the groove is the first step; the full practice — repetition, metronome, audio, progressions and review — happens in Chord & Fret. There this pattern stays saved in your study, to revisit later, play offline and track your progress.
