Samba guitar rhythm: thumb and finger block
The samba guitar rhythm in 2/4: the thumb plays the bass (B) and the i-m-a fingers answer with the chord as one block (A). Beat by beat, one mark per sixteenth note, with · where there is no stroke: BA·A B·A·.

Sound summary
For the guitar, Samba uses a bass-and-chord figure, in 2/4 straight (even subdivisions): the bass (B) comes from the thumb and the chord (A) follows. To the ear: B A — A B — A —.
How to count it
In 2/4, each bar has 2 beats, 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
B = bass (thumb) · A = chord block (i-m-a together, no sweep) · — = no stroke
The thumb bass and the i-m-a block follow the two-voice violão notation (Silva & Madeira 2021).
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. It is a pinch: the thumb stays on the bass strings and i-m-a pull the three treble strings together — never sweep across all the strings. On the rests the hand stays put: the fingers hover over the strings, ready for the next block.
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 C
Over a C chord, the bass (B) is the note G on the low string — the chord’s lowest note. Play that bass on the pulse and let the whole C 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.
- Running the subdivisions. The faster the pattern, the easier to push ahead — lock the tempo on the metronome before speeding up.
- Freezing the arm on a rest. It should keep going in the air, off the strings, and land on the next hit — the continuous motion is what holds the time.
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.
- Add the two voices. Bass then chord, always in that order, slow, until it plays itself.
- Take it up on the metronome. Start slow, keep the pattern clean, and add a few BPM at a time.
You already get the logic of the groove. Now put it in time: hear the pattern, follow the count and practice slowly until the bass and the chord sit apart in time. In Chord and Fret, the Metronome and the Rhythm Trainer help with that drill, free.
