With 37 confirmed trio sonatas to his credit, Giuseppe Tartini is the most important Italian composer of his generation for this type of repertoire. It may seem odd therefore that these works have been so sorely neglected; indeed, as of 2022 only around 20 per cent of the repertoire had been recorded and a critical edition had yet to be published. This state of affairs was largely due to confusion regarding sources, with many divergent interpretations and uncertainties regarding the dates of the handwritten scores. Some order has been brought to this originally chaotic situation by the research carried out by Juan Mariano Porta from 2018 to 2022 as part of his doctoral studies, the result of which was the inclusion of the trio sonatas in the upcoming publications of the Edizione Nazionale delle Opere di Giuseppe Tartini, with advance materials made available to the Il Demetrio ensemble for recording. Giuseppe Tartini dedicated almost all his energy to his chosen instrument, the violin. His established corpus of works currently numbers 200 sonatas for violin and bass, 150 violin concertos, 37 trio sonatas, a handful of concertos for other instruments, and a small number of quartet sonatas and vocal compositions. Production of the trio sonatas began in the composer's late-mature years, and their style would seem to correspond to Tartini's final compositional period, described as a Drang nach absoluter Musik [urge for absolute music], which began around 1750 without a clear line of demarcation from what came before and continued until the composer's death. The trend was towards simplicity, partly deriving from Tartini's desire to put his theoretical speculations into practice. The trio sonatas no longer feature the virtuoso passages of earlier works. They present a binary form with regular phrasing. Their harmonic rhythm is slow, with the violins mainly proceeding in parallel triplets. The function of the bass is relegated one of harmonic support. This recording contains the sonatas G1, D1, d1 A1, A2, A3, A6, and a1, which date to Tartini's final compositional sub-period. They are little-known pieces, most of them hitherto unpublished.
