The Slovenian style polka band always includes a piano accordion, chromatic accordion, or the Diatonic button accordion (also called a "button box"). Some bands in Slovenia use keyboard instead of accordion. The other melody instrument is a saxophone or clarinet, and the rhythm instruments include drums, bass, and guitar or banjo. Avsenik brothers add a trumpet, too. The Slovenian style polka in the United States of America came about when immigrants from Slovenia taught the old songs to their children. Those children, as adults, translated the old songs from the Slovene language into English, and arranged them in a polka beat.
At first Slovenian style polka was just music for ethnic clubs and union halls, but the commercial success of Frankie Yankovic (Jankovič) and other musicians soon introduced the genre to a wider audience. William Lausche incorporated the elements of classical music and early jazz at which point the style took on a type of swing that can be heard in his piano playing, even on some early Yankovic recordings. Johnny Pecon and Lou Trebar consequently extended the style to its farthest reaches harmonically, including blue notes, substitutions and compounded symbolism, elements of whole-tone scales, modality, borrowed and altered chords homophonically or in the implied or broken form and compounded and odd rhythmic embellishments or reductions, in addition to the use of structural and textural dynamics and phrasing that had up to that point never been utilized to such a degree.
In addition to Frankie Yankovic, the most important pioneers in developing this style of music include Matt Hoyer, Dr. William Lausche, Johnny Pecon, Lou Trebar, Johnny Vadnal, Eddie Habat, and Kenny Bass.
