The Istrian scale is a distinct hexatonic musical scale in the regions of Istria and Kvarner in Croatia. It is used in Istrian and Kvarnerian folk music. Non-equal-tempered, the scale could approximately be notated as: E-F-G-A♭-B♭-C♭.
Something like the Istrian mode, but without its top note, is found in Haydn's String Quartet in F minor, Op. 20 No. 5.
