That's how it's yuwalktja (really) meant for, yidaki. For Yol\u, balanya nhakun (for example), for mine, Djapu, Djapu nh^wuku (for my Djapu clan), manikaywu (for the songs), it's got other tune, for my manikay (songs).
Gumatjku, tune nhan\u g^nayany (For the Gumatj clan, his tune - referring to the nearby Gumatj man Miniyawany Yunupi\u - is different/separate). Didjeridu nhan\u (his) play for only Gumatj.
Ma\galili, Dhalwa\u (two other Yirritja clans) same. Different yidaki and tune for each one. Because these tribal people got different different manikay.
