Chord & FretSamba rock · Cavaquinho
Samba-rock
Sound summary
Samba rock is played with a chord strum — 2/4, straight (even subdivisions) — for the cavaquinho: the chord (A) swings back and forth, down and up, with muted hits (x) driving the groove. It sounds like this: A↓ (x) (A↓) A↑ (A↓) (x) A↓ (x) (A↓) A↑ (A↓) (x) A↓ (x) (A↓) A↑.
How to count it
The meter is 2/4: 2 beats per bar, counted in sixteenth-notes (four per beat). Count out loud: 1 e & a, 2 e & a. Tap your foot on the strong beat and read the grid above: each cell is one subdivision.
The rhythm grid
A = chord · ↓ down-stroke · ↑ up-stroke · x = muted · (x) = ghost (light graze)
The ↓/↑ direction follows the bowed-string arcada convention (ᴨ down, V up; Ribeiro 2017). The muted and ghost strokes follow Cantalice 2022.
How to play it
Right hand
Alternate down (↓) and up (↑) on the chord (A). The down-stroke is firm; the up-stroke just grazes the thin strings — that contrast gives the bounce. On the (x) hits, mute: rest the hand on the strings at the attack for the percussive “chka” that gives the groove its bounce.
Left hand
The left hand gives the harmony: hold the whole shape clean from start to finish, leaving the right hand to the rhythm. Make the change on the last beat, the hand already heading to the next chord. For the (x), loosen the fingers without lifting off the strings — they go silent but stay put, ready to ring again.
Example in G
Hold a G and apply the whole pattern to it — every hit lands on the same chord. That’s how you take the groove into any song: change only the left hand, the right hand’s rhythm stays the same. Hear the example below.
Common mistakes
- Letting the (x) ring like a note. It is percussion, not chord — if you don’t mute, the groove loses the “chka” that drives it.
- Weighing down the up-stroke. The up (↑) should just graze the thin strings; matching the down-stroke’s force thickens it and drags the time.
- 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
- Start all down. Strum the chord down (↓) on every stroke, one direction only.
- Bring in the up-stroke. Let the arm rise (↑) lightly between hits, grazing the thin strings.
- Bring in the (x). Lay the hand on the strings on those hits so the percussive “chka” enters the groove.
- Close with the metronome. Go slow first and raise the BPM only once the pattern comes out clean.
You’ve got the theory; now the time has to enter the body. Play along with the audio, follow the count and raise the metronome bit by bit until every stroke lands in its place without rushing — Chord & Fret runs that drill with an adjustable tempo.
Train with the metronome →Variations & related patterns
With the strum steady, take it to actual Samba rock progressions: rhythm, chord changes and voice-leading in one exercise. That’s the Progressions by Rhythm feature in Chord & Fret.
