The siku (Spanish Zampoña), is a traditional Andean panpipe. It is the main instrument used in a musical genre known as sikuri. Traditionally it can be found all across the Andes but more typically it is associated with the speaking regions around Lake Titicaca. Historically, because of the complicated mountain geography of the region, in some areas each community would develop its own type of siku, with its own special tuning, shape and size. Additionally ,each community developed its own style of playing.
Today the siku has been standardized to fit in with modern western forms of music and has been transported from its traditional roots.
