"Istrian scale" refers both to a "unique" musical scale and to the Istrian and Kvarnerian folk music genres which use the scale. It is named for the Istrian peninsula. Genres include kanat and tarankanje; techniques include nasal tone, variation and improvisation, and resolution to the unison or octave; and instruments include sopele shawms, bagpipes, flutes, and tambura lutes. It was first named by Ivan Matetić Ronjgov early in the twentieth century, assisting his study and notation of Croatian music.
