Here’s the drum transcription of the intro performed by Brazilian drummer Erivelton Silva on Rosa Passos’ tune “Beiral,” from the album Morada Do Samba (1999). In this section, the ensemble accents are similar and related to Partido Alto.
Erivelton Silva plays the hi-hat accenting for the most part the third 16th note, supporting the ensemble accents with the bass drum and the snare cross stick.
