Beethoven , Violin Concerto in D Major, op. 61, mm. 273-296 - Jenkins

 The first modulation in this excerpt occurs in the second beat of measure 278. It begins in D major and modulates to A major through the use of G sharp. It is a short modulation; however, the cadenza ensures a modulation. This relationship can be distinguished as relative keys, A major being the Dominant key to D major. The piece returns to D major briefly in measure 282. Through the use of a chromatic mediant (G reaming natural in both keys), The piece appears to bein modulating to Ab major in measure 286. The piece remains in Ab major until what sounds to be a Half Cadence at the end of measure 296. Nonetheless, there are moments throughout the piece where it is hard to distinguish a "Do." For example, when listening to a recording, there is a moment when the piece sounds minor. I believed this to be chromatic tones, as there is no clear cadence to establish a modulation.
