Abstract
The Corelli trio sonatas are emblematic of the mid-Baroque period, characterized by their elegant melodies, intricate counterpoint, and systematic development of thematic material. Extending harmonic annotations from Hentschel et al. (2021), we provide a dataset with annotations of all 38 slow movements of the Sonate da chiesa Op. 1 (1681) and Op. 3 (1689), focusing on this Baroque writing style. The 7,000+ annotations describe the texture (homorhythmy, imitations, suspensions), further detailing thematic and imitation patterns, with other information such as rhythmic density. We provide audio synchronizations to a widely available recording and release the corpus for download as well as through the Dezrann platform.
