It is used as a rhythm and melody instrument in the Andean region of Ecuador during festivals where dancing and music are involved.

In the Andean region of Ecuador, the bandolin is used during the celebration of the feasts of San Juan and San Pedro, along with several other instruments including: twin flutes, guitars, violins, quenas, a drum, a charango, a rondador, and a harmonica.

The bandolines and the guitars mark the 2/4 tempo of the sanjuanito rhythm, which is accentuated by the bombo, and the quenas, rondador, and violins carry the melody.

[1] The body shape of the bandolin is similar to that of the bandola, the cuatro, or the guitar, with the caveat that, just as in the case of the mentioned instruments, luthiers who produce bandolins will incorporate into their personal designs changes to the body shape for a variety of reasons.

The 15 strings run over a floating bridge to a metal tailpiece on the end of the body.
