 In the Surakarta tradition, only "pathetan", "sendhon" and "ada-ada" are recognised as forms.A further distinction between types is between those accompanied by a small group an instruments including "gendér", "gambang", "rebab" and "suling" (such as "lagon" and "suluk"), and those accompanied by gender alone or with the addition of "kempuls" and "gongs" (such as "kawin, sendhon" and "ada-ada").All sulukan have a specific "pathet" designation relating both to the mode of the "gamelan" and the act of the "wayang" performance, many also have a functional specification relating to their role in the drama, which either specifies the scene in which they are used or their particular occasion.
