The Undine Sonata for flute and piano is one of the few works by the composer Carl Reinecke which is regularly performed even today, and is at the same time one of the few Romantic repertoire pieces for transverse flute. Although not obviously programme music at first glance, and sometimes even questioned as such by contemporaries, the work nevertheless falls back on the Undine subject which was a popular opera theme in the 19th century. The Wiener Urtext Edition now presents a new publication of the work which closely follows the text of the original edition (unfortunately, manuscript sources are not extant). The notes on interpretation follow the tracks of the extra-musical programme, trying to bring the work and its interpretative understanding into close connection with the Undine subject.
(...) This edition is clearly printed with more than the usual space between staves, allowing the performers to add their own notes and performance reminders without duttering the page. Marvellous! The music can breathe.
This cleansed edition, it seems to me, offers new performers the chance to evaluate all the options that have surfaced from the latest research and make up their own minds, whilst offering the experienced player a chance to modify or start afresh.
