Cadenzas to Horn Concertos Cadenzas to Horn Concertos by Joseph and Michael Haydn The present publication encompasses cadenzas to four horn concertos by the brother-composers Joseph and Michael Haydn. Among the four works, the authenticity of only two is ascertained: Joseph Haydns Horn Concerto in D Major, Hob.VIId:3, and Michael Haydns Serenade MH 86, from which the two-movement Concertino for Horn and Alto Trombone is extracted. Of the other two works, the Horn Concerto MH 53/Hob.VIIb:4 has been ascribed in different sources to either composer, but is possibly the work of yet another, unidentified composer. Doubts exist also with regard to the authenticity of Michael Haydns Horn Concertino MH 134. The cadences presented here were composed in conjunction with a recording of all four works by the soloist PYemysl Vojta and the Prague Haydn Ensemble conducted by Martin Petrák. In his famous flute treatise of 1752, Johann Joachim Quantz writes regarding the solo cadenza: The aim of the cadenza is to surprise the unsuspecting listener at the end of the piece and to leave behind some special impression. With this in mind, I sought in the present set of cadenzas supplied for Joseph and Michael Haydns horn concertos to engage in an original, unexpected dialogue with the musical material of the respective movements. All cadenzas carefully observe the limited choice of notes available on the natural horn written for by the Haydn brothers.
