Peruvian cumbia

Chicha or Peruvian cumbia is a subgenre of Cumbia that became popular in the coastal cities of Peru, mainly in Lima in the 1960s through the fusion of local versions of the original Colombian genre, traditional highland huayno, and rock music, particularly surf rock and psychedelic rock. The term Chicha is more frequently used for the pre-1990s variations of the subgenre. Unlike other styles of cumbia, the Chicha subgenre's harmonics are based on the pentatonic scale typical of Andean music. It is played with keyboards or synthesizers and up to three electric guitars that can play simultaneous melodies, an element derived from the harp and guitar lines of Andean huayno. The rhythmic electric guitar in chicha is played with upstrokes, following patterns derived from Peruvian coastal creole waltz. Chicha songs contain electric guitar solos, following the rock music tradition.
