 Some Schwyzerörgelis have fewer buttons in the upper/inside row on the RH much like the club models, or more buttons - sometimes an extra row on the outside - and fewer or more basses.Since Swiss music rarely uses minor chords, even Örgelis with 4 bass rows usually have no minor chords but majors and 7ths instead.The only other variety still being made in substantial numbers today is the Schwyzerörgeli with chromatic fingering, usually with a C system (C-Griff) treble side and Stradella bass fingering.
