Since Laurence Feininger attributed the Missa Puisque je vis to the composer Dufay in his 1963 edition, the work has been perceived as being on the periphery of the Dufay canon.[2][5] Although this attribution was initially controversial, recent research increasingly supports Feininger's view. In a previously unpublished monograph, Feininger attempted to present his arguments in detail, lending particular weight to his attributions.
Listening to the mass confirms the persuasiveness of Feininger's thesis. Dufay's distinctive musical language is clearly recognizable and places the Missa Puisque je vis on a par with other masses whose authorship is unequivocally attributed to Dufay.[2] Like the Missa Ecce ancilla Domini, which probably originates from a similar creative period, this work also impresses with its open structure and elegant melodic lines.
Like many settings of the Mass from the late 15th century, the Missa Puisque je vis is based on a courtly song that honors the Virgin Mary as intercessor for humanity.[2] The text of the underlying song, attributed to Dufay himself in several manuscripts, conveys an ambiguous yet profoundly laudatory message. The motet Omnium bonorum plena by Compère also focuses on the intercessory role of the Virgin Mary.[4]
Another notable work from this period is Concede nobis, Domine, whose style reflects earlier aesthetic approaches. Likewise, Salve maris stella and other 15th-century motets deserve attention because they express a specific plea for intercession. Salve maris stella is thought to be connected with historical events surrounding Henry VII of England.
Dufay's work, a sung prayer of great depth, continues to move people centuries later. There are indications that Dufay himself prayed for a reduction of his time in purgatory, and this work was performed at his funeral rites the day after his death. This clearly distinguishes it from the usual Marian antiphon.
The exceptional expressiveness and unexpected musical structure lend Dufay's compositions a uniqueness and emotional impact that continues to resonate today. His works speak to the emotions of later generations and demonstrate remarkable creativity in musical composition.
