The first movement, in 12/8 time, begins gently and reflectively, with languid double stops and a flowing violin melody line filled with tasteful embellishments.The melody, which moves from the tonic to the dominant key in the middle of the movement includes several deceptive cadences, before returning once again to a tonic theme similar to the beginning.A crisp, quick, highly decorated bravura follows, preceding a brief cantabile slow movement, said to signify Tartini's dream state.The last movement, technically difficult, begins fast, before dissolving into repeated, modular violin melody over an intensifying accompaniment. This leads to a slow chromatic theme, followed by more sequences of the two themes, before a bravura cadenza begins, with trills outlining the main theme. This cadenza is the source of the sonata's nickname. The accompaniment joins the violin again for the last few dramatic measures.The trill in the last movement is one of the earliest examples of a trill illustrating a musical theme.
