The twenty pieces comprising the musical collection in the Codex Trujillo del Perú are an exceptional case in the history of the indigenous music of the New World. This collection of tonadas, cachuas, tonadillas, bayles, cachuytas and lanchas offers a glimpse of the repertory native to the traditions of the country, as indicated by the text of one of the cachuas sung “al uso de nuestra tierra” (“according to the customs of our land”) and in particular the songs and dances favoured by the popular classes who lived in the “Viceroyalty of Peru” at the end of the 18th century.
