'JUPITER: Mozart in the 19th-Century Drawing Room' challenges our preconceptions about the way in which Mozart's music was consumed in the early 19th century in two important ways: it confronts us with arrangements for piano, flute, violin and 'cello (the 'JUPITER' ensemble) of Mozart's best-known symphonies, concertos and overtures and sets them in the performance context of the 19th-century drawing room. The project takes the knowledge that has been gained from the AHRC-funded 'Mozart's Ghosts' (three related projects), and engages with communities on which the original project had little or no opportunity to make any impact. The original research undertook a wide-ranging approach to questions of Mozart reception, and along the way identified a repertory of Mozart's large-scale concerted music (concertos, symphonies and overtures) that was arranged and published, almost exclusively in London, for the JUPITER ensemble. The music thus arranged was the basis of the ways in which these works were experienced in early 19th-century Britain, whether in luxurious townhouses or the provincial homes of the more modest gentry. 'JUPITER' takes the opportunity to reveal to beneficiaries and user-groups a musical culture that is completely unknown today, and to explain how Mozart's large-scale works were consumed outside the rarefied, and largely urban culture of the city concert. With a project team consisting of PI Everist, RA Hewlett and four artist-researchers, 'JUPITER' will take AHRC-funded research and transform the experience of a variety of beneficiaries. The original project made its impact via conventional verbal presentations, largely in response to requests to speak rather than as a coherent project of engagement; it uncovered significant amounts of material that revealed a key question that should be legitimately asked of early 19th-century musical culture: how was Mozart's large-scale concerted music performed beyond the simple piano arrangement? The answer emerged in the form of the 'JUPITER' ensemble. The ensemble takes its name from the edition of Mozart's last symphony that first used the now-unassailable title 'Jupiter'; the print was published in London in 1822 and the work arranged by Clementi for the JUPITER ensemble. A tiny number of these arrangements have been published in modern times, but the performance medium has yet to make any impact, a situation that the current project transforms. The key pathways to impact consist of a network of partnerships, a series of innovative and interactive workshops, together with audio and video engagements. All our concert promoters or festival managers have responsibilities both for developing audiences and for promoting public engagement with other bodies. A series of workshops will explore various routes to engage with communities that extend beyond those who consumed the textual outputs produced by the original research. To do this we will approach questions of comparison (between originals and arrangements), organology and cultural environment, as well as presenting introductions that characterise the current form of lecture recitals and similar events. While this part of the project will engage in depth with some of our user groups, a commercial CD recording will increase the reach of the impact, and a web-mounted video will further explain the nature of music-making and the audience in the early 19th-century drawing room to further groups of beneficiaries. We will monitor, evaluate and document the impact that the research makes. Our central tools are the anonymous questionnaire, the one-to-one interview, the CD and the video recording; these documents and their analysis will form the lasting legacy of the project, and will be mounted on its website to serve as materials and a prompt for other ensembles wishing to undertake similar work, or will be made commercially available.
