The CD synthesises some stages characterising the composition path of Pier Paolo Scattolin: from a cappella vocality to instrumentalism with stylistic dynamics sometimes distant but all having in common the research on sound, from the linguistic phoneme to the eclectic and sometimes experimental use of instrumental emission. The path winds through almost forty years of continuous investigation and dissection of both choral and instrumental sound, the latter of a chamber/soloistic character and in some cases concerted and intersected with the voice. In the a cappella choral repertoire a varied anthology collects poetic and literary texts by Dante Alighieri, Giuseppe Ungaretti, Alda Merini, Umberto Saba, Emily Dickinson, Alessandro Striggio, Agnolo Poliziano, Alceo, Sappho, Ipponatte, Enzo Iacchetti, Agnese Troilo and the composer himself. Some choral pieces are concerted with the Ensemble of ancient instruments Circe from Bologna, whose presence stems from the search for a sound language proceeding towards the stripping and essentiality of a music and a sound coherent with the setting of the poetic texts in order to transfer their instrumental characteristics to contemporary musical expression. In some pieces the solo voices are added as an almost instrumental colour, a timbre enrichment of the sonorities of the organ, the recorders, and the trumpets.
