Slovenian/Oberkrainer style accordion rhythm is a technique used by Slovenian and Austrian alpine style accordionists to complete the rhythm section in a trio or quintet, by playing chords repeatedly as semiquavers in polkas, or quavers in waltzes. In Slovenian it’s known as ‘tresenje‘ (shaking), for its ‘shaking’ sound, and ‘spremljavo‘ (accompaniment). In German it’s called ‘Oberkrainer begleitung‘ (Oberkrainer accompaniment). In trios with vocals, or quintets with a trumpet and clarinet, the accordion never only sticks to melody or rhythm, but fluidly alternates between melody and rhythm.
