Their music is characterized by melodic vocal harmonies, polished studio arrangements, danceable mid-tempo tracks and sentimental lyrics about love and relationships. Each duo has been active in recording albums, releasing singles and performing widely in Brazil, helping to shape the sound and commercial orientation of modern sertanejo.
