Sindhènan Pêmatut in Surakarta-Style Karawitan: Vocal Decision-Making in Context-Dependent Garap

This study examines sindhènan pêmatut, the context-dependent adjustment of female vocal practice, in Surakarta-style karawitan (Central Javanese gamelan performance) as an adaptive mode of vocal garap (interpretive working-out in performance) that becomes operative when standard placement schemes and melodic conventions do not adequately fit the musical conditions of a gending or a formally structured gamelan piece. Rather than treating pêmatut as an aesthetic preference, the study frames it as a set of decisions through which pêsindhèn (female gamelan vocalists) maintain coherence across irregular forms and regular forms with atypical phrase organisation. The findings identify three interrelated dimensions of sindhènan pêmatut: 1) adjustment of wangsalan placement according to padhang-ulihan phrase function and cèngkok; 2) cèngkok-based adaptation shaped by rêbab garap, register, and balungan patterns such as ngadhal and nggantung; and 3) cakêpan-based substitution influenced by ensemble texture and gending theme. Overall, sindhènan pêmatut emerges as a context-dependent decision process that sustains vocal coherence when schematic conventions are insufficient.
