'Sometimes the symphonies ů are destined to showcase the musicians' talents'' - a music dictionary of the time thus commented on a new genre, the ''Symphonie concertante''. The playful competition between the solo instruments proved very popular with the audience and sparked rivalry between the concert organizers in the music metropolis London: Ignaz Pleyel received a great deal of praise for one such ''concertante'' and only four weeks later Haydn achieved great fame for Hob. I:105. This attractive work is now published in piano reduction so that it can be played without orchestral accompaniment. The performing material is published by Barenreiter.?
