Founded in 2012 by Cecil Gallois and Xavier de Lignerolles, the Ensemble Tarentule carries out research and dissemination work on the interpretation of polyphonic a cappella music. This exploration, seen through the prism of the madrigal at the end of the 16th century, is extended and enriched by the creation of a contemporary repertoire, in connection with the composers of today. The musicality of the Ensemble is due to the color of the voices which complement each other and have become accustomed to working together since its creation to find a perfect harmony and a specific sound - like the members of a string quartet. It therefore achieves great consistency and fluidity with finesse and contrast. Gesualdo's Fourth Book of Madrigals is rightly considered the collection of the author's artistic and aesthetic maturity. After two books of a classic invoice, where the strict counterpoint rubs shoulders with a sober and little chromatic modality, he begins from his Third book a stylistic evolution in the movement of the works of Luca Marenzio and Luzzasco Luzzaschi, both supporters of a style on -expressive, exacerbating chromaticisms, affective figuralisms and a counterpoint to the limit of rupture. In his Fourth Book, Gesualdo fully masters his material and allows himself to be daring. Relying on very short poems, he can chisel each sentence, each word, giving them various colors, searching all the nuances of the affections of the soul.
