Brazilian percussion

▶ Open in Aratu to hear the examples, change them and do the exercises

The drum kit has one symbol per piece. Brazilian percussion is different: each instrument has a line of its own, named after the instrument, with its own strokes: the thumb on the pandeiro, the bacalhau on the zabumba, the triangle open or closed. The rhythm follows the same rules as always.

A line named after the instrument

Write the instrument's name before the =, and use the letters of its strokes:

tempo: 100
triangle = fo fo fo fo

f is the closed triangle (the hand holds the metal) and o is the open one (the hand lets go and it rings). That "closed, open" in eighth notes is the heart of the baião.

Line	Strokes
`pandeiro`	`p` thumb, `d` fingertips, `t` slap, `m` muted
`zabumba`	`o` open, `m` muted, `b` bacalhau (the thin stick underneath)
`triangle`	`o` open, `f` closed
`agogo`	`a` high bell, `g` low bell
`surdo`	`o` open, `m` muted
`tamborim`	`o` open, `m` muted
`alfaia`	`o` open, `m` muted
`gongue`	`o` open, `m` muted
`shaker`	`s`
`cuica`	`a` high, `g` low
`cajon`	`b` bass, `t` slap

The names keep their Brazilian spelling because they are the instruments' own names. The pandeiro is the Brazilian frame drum with jingles; the zabumba is the wide bass drum of baião and forró, struck with a mallet on top and a thin stick, the bacalhau, underneath; the agogô is a pair of bells; the surdo is the big bass drum of samba; the tamborim is a small, high frame drum played with a stick; the alfaia and the gonguê (a large iron bell) come from maracatu; and the cuíca is the friction drum that "talks" in samba.

A name may be written with or without its accent (agogô or agogo), and in Portuguese or Spanish too (triângulo, ganzá, cajón). agbe, caxixi and chocalho play like the shaker.

If you write a letter the instrument does not have, x on the pandeiro for example, Aratu tells you which strokes it has.

The baião

The baião brings three instruments together: the zabumba, the triangle and the agogô (or the accordion, which comes later). The zabumba plays the open stroke on beat 1, the muted one at the end of beat 2, and the bacalhau answers underneath:

tempo: 110
zabumba  = | o - -o m | o - b - |
triangle = fo fo fo fo
agogo    = a g ag -

Change the tempo to 140 and the baião turns into forró pé de serra.

The samba

In samba, each instrument has its role. The surdo marks beat 2, the tamborim plays the figure, and the pandeiro and the shaker fill in the sixteenths:

tempo: 96
meter: 2/4
surdo    = m O
tamborim = o-oo -oo-
pandeiro = pdtd pdtd
shaker   = Ssss Ssss

Samba is counted in two. An upper-case letter is an accent, as on the drums: O on the surdo is the strong stroke of beat 2, and S on the shaker marks the start of each beat.

With the drums

Percussion lines play together with the drums and the other parts. In Brazil the drum kit's floor tom is also called surdo, but in Aratu a surdo line is always the samba surdo; the floor tom is still f, on a drum line:
