According to several sources, Arcangelo Corelli studied under the papal contralto and composer Matteo Simonelli after arriving in Rome in the early 1670s. The Russian biography states that from 1671 Corelli lived in Rome, where he studied counterpoint with Matteo Simonelli, who himself worked in the Palestrina tradition. This places their teacher–student relationship in Rome during Corelli’s formative period as a young musician.
English‑language sources add that later reports claimed Matteo Simonelli taught Corelli to write in the "Palestrina style", though the reliability of these accounts is not fully confirmed. Nevertheless, Simonelli is consistently cited as the figure who introduced Corelli to advanced counterpoint techniques in Rome, shaping an important part of his early musical training.
