Chord & FretCumbia · Guitar
Cumbia Offbeat (bajo-contratiempo)
Sound summary
The Cumbia pattern is a bass-and-chord figure for the guitar, in 4/4 straight (even subdivisions): the bass (B) comes from the thumb and the chord (A) follows. It sounds like this: B A↑ B A↑ B A↑ B A↑.
How to count it
The meter is 4/4: 4 beats per bar, counted in eighth-notes (two per beat). Speak the count: 1 e, 2 e, 3 e, 4 e. Keep the beat with your foot and follow the grid: each box is one subdivision.
The rhythm grid
B = bass (thumb) · A = chord · ↑ up-stroke
The ↓/↑ direction follows the bowed-string arcada convention (ᴨ down, V up; Ribeiro 2017).
How to play it
Right hand
Bass and chord take turns: the bass (B) on the thumb first, then the chord (A) answering — always in that order, never colliding.
Left hand
The fretting hand holds the chord firmly through the whole pattern — it owns the harmony while the right hand owns the rhythm. Change chords at the last instant of the bar, the hand already moving toward the next shape.
Example in Am
Over an Am chord, the bass (B) is the note A on the low string — the chord’s root. Play that bass on the pulse and let the whole Am answer right after. Hear the example and follow the diagram.
Common mistakes
- Bass and chord landing together. The bass (B) comes first; the chord (A) answers after. If they collide the groove disappears — separate the two hands in time.
- Up-strokes as hard as down-strokes. The up-stroke (↑) is lighter and catches only the treble strings — equal force thickens and drags it.
- Rushing. Fast subdivisions are easy to run. Start slow with the metronome and only speed up once the pattern is clean.
- Letting the tempo drift. Without a firm pulse the strum leaks — count along and hold the same time from the first bar to the last.
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.
Train with the metronome →Variations & related patterns
With the strum steady, take it to actual Cumbia progressions: rhythm, chord changes and voice-leading in one exercise. That’s the Progressions by Rhythm feature in Chord & Fret.
