The present Trio in E flat major, published for the first time, is on a par with the op. 1 for beauty of sound and instrumental grandeur. Our source for the Trio is a copy of the parts kept in the Archives of the Sing-Akademie in Berlin under shelfmark SA 3439. The separate title reads: '[Incipit] / Sonata da Camera / a 3. Cantariden / Oboe Violino / e / Basso Cembalo / di Sigr. Janitsch / No: 133.' The bass part is amply figured. At the end of the second movement (Allegretto), the violin part contains cadenzas for both violin and oboe.
