For SATB Voices, a cappella
Arranged by Marco Antonio da Silva Ramos
Moreninha, se eu te pedisse is a "modinha", a very widespread music genre in late XIXth Century Brazil, specially so in the Southeast region. This arrangement was created to sound like a melody, as if accompanied by a seven-string acoustic guitar, itself a very common instrument in southern Brazil.
The indicated dynamics and tempos are quite precise, suggesting a clear way to perform it, however the entire song must be performed with some rubato, as a romantic lied.
