Premieres and sensational finds are rare but there are still miracles happening: there is hardly any other composer whose life and work have been better researched and of whose complete works we have such a precise listing. Above all, because his enterprising father Leopold had compiled a catalogue of compositions by his child prodigy already in 1768. Now the almost impossible has occurred: a new, completely unknown work by Mozart has surfaced! The Allegro in D major K 626b/16, a three-part, dance-like piano piece lasts a total of 94 seconds. Examined for authenticity by the best international Mozart scholars, it is being performed for the first time ever in Salzburg, the birthplace of the great genius. But for what occasion was it composed, how was it handed down? Ulrich Leisinger, scientific director of the Mozarteum Foundation, answers these questions in conversation with Rolando Villazón. This lecture is embedded into a concert program starring Korean pianist Seong-Jin Cho and putting the new work into context.
