Hendrik ("Henk") Temmingh word vandag gereken as een van Suid-Afrika se mees toonaangewende orrelkomponiste. Hy het sy veelsydigheid bewys en veral gevestig geraak as 'n noemenswaardige figuur op die gebied van die improvisasiekuns en orrelmusiek. Min publikasies oor Henk Temmingh se orrelwerke het tot dusver verskyn, daarom blyk dit dat die eerste logiese stap om hierdie leemte te vul die opstel van 'n katalogus sal wees. Verskillende aanbiedinge ten opsigte van katalogusopstelling word in die groot verskeidenheid beskikbare katalogusse bespeur. Daarom moes hierdie katalogusse, asook die verskillende data-versameltegnieke ondersoek word om te bepaal wat die wesenlike inhoud van so 'n nuut-saamgestelde musiekkatalogus behoort te wees. Met behulp van die chronologiese katalogus van Temmingh se orrelwerke kan 'n onmiddellike oorsig van sy bydrae as orrelkomponis nou verkry word. Hierbenewens sal die nuut-toegekende katalogusnommers 'n aanduiding gee van waar die betrokke orrelwerke chronologies by Temmingh se oeuvre inpas.
Hendrik ("Henk") Temmingh can be regarded as one of South Africa's leading organ composers. He showed versatility and established himself as a significant figure in the fields of improvisation and organ music. Few sources concerning Temmingh's organ works are available. In order to fill this hiatus, the first logical step would be to compile a catalogue. Different styles and approaches concerning the compilation of catalogues can be observed in the wide variety of catalogues available. Therefore, these catalogues, as well as data compilation techniques had to be investigated in order to determine what essential information should be included in such a newly compiled catalogue. An immediate summary of Temmingh's contribution as an organ composer can now be obtained with the help of the chronological catalogue of Temmingh's organ works. Apart from this, newly allocated catalogue numbers will give an indication of where the works concerned chronologically fit into Temmingh's oeuvre.
