Peruvian music has Andean, Spanish, and African roots. In pre-Columbian times, musical expressions varied widely in each region; the ''quena'' and the ''tinya'' were two common instruments. Spaniards introduced new instruments, such as the guitar and the harp, which led to the development of crossbred instruments like the ''charango''. African contributions to Peruvian music include its rhythms and the ''cajón'', a percussion instrument. Peruvian folk dances include marinera, tondero, zamacueca, diablada and huayno.
