Hummel’s quoting of music by other composers has been mentioned briefly in a number of studies. While some of these quotations are explicit, others are a good deal more problematic. This article investigates explicit quotations that appear in two of Hummel’s string quartets dating from 1803–1804 and the finale of a piano sonata from 1807. The fourth movement of the String Quartet in G major, Op. 30 No. 2, twice quotes J. S. Bach’s Goldberg Variations, BWV988, the slow movement of Op. 30 No. 3 refers to Handel’s Messiah and the finale of the F minor piano sonata cultivates a complex relationship with the last movement of Mozart’s ‘Jupiter’ Symphony. My objective is to demonstrate the sophistication and subtlety with which Hummel manipulates the quoted material in these three cases.

Hummel’s obvious quotation of Bach and Handel in particular is related to a multi-faceted preoccupation with archaic styles and earlier works that had taken root in the later eighteenth century and that continued to expand into the nineteenth and beyond. Although England was the first nation to develop a performance tradition around the ‘ancient’ musical repertory, it was the accumulation of a didactic tradition around the keyboard works of J. S. Bach in north Germany and its steady migration to centres like Vienna that is of more direct relevance here. And when one surveys the (supposed) quotations by Haydn, Mozart, Beethoven and Clementi of works by Bach and Handel and compares them with Hummel’s, Hummel’s remain outstanding in their exactness and also in their frequent lightheartedness of tone. Whereas many straightforward quotations or instances of modelling appear reverential or seek to exalt the basic idiom, Hummel’s either are humorous or seem calculated to reduce the potency of the original in order to assimilate the earlier idiom into the later one. The three pieces considered here illustrate the spectrum of techniques used by Hummel to manipulate quoted material in his works. The quotations in the two quartets have drawn very little comment; the references to Mozart’s ’Jupiter’ Symphony in the finale of Op. 20 have been remarked on more frequently, but the relationship between the two finales is a good deal more intricate than has previously been shown. The ‘contrapuntal deconstruction’ that takes place late in the third movement of Hummel’s Op. 20, between the most explicit reference to the ‘Jupiter’ finale and the coda, is lighthearted in character – amusing, even – and is in some ways the most ingenious and vibrant episode in the movement.
