a 6 et a 8-The Serenade in E-flat K.375 exists in two versions one for two clarinets two horns and two bassoons and another for the same forces plus two oboes forming an octet.From Mozart himself we know a fair amount about the occasion that led to the first six-instrument version of this work and about its early performances. Written for the sister-in-law of the court painter Hickl it probably originated toward the end of September or the beginning of October in 1781 and was first performed on 15 October the name-day of St. Theresa.The octet version probably arose in the summer of the following year. It is far more than a mechanical expansion of the sextetwith the oboes merely reinforcing the clarinets colla parte. Not only did Mozart take advantage of the occasion to make changes in the articulation and the dynamics he also altered the work’s melodic substance and formal design. The two additional high-register instruments allowed him to achieve more subtle distinctions and gradations of timbre thereby enabling him for example to vary the timbral homogeneity of the two clarinets. The opportunity arose to divide melodic phrases among the clarinets and oboes or to make them more brilliant and incisive by doubling them at the unison or octave.- Urtext of the New Mozart Edition- Parts sextet version (BA5333) octet version (BA5334) and study score both versions format 22.5 x 16.5cm (TP315) available for sale

Dramma giocoso (Opera) in two acts-In early 1787 Mozart made his first visit to Prague where he attended a performance of Le nozze di Figaro on 17 January and conducted the performance five days later. Thoroughly impressed by the huge success of his opera and the personal triumphs he had enjoyed during his visit he and his wife left the city on 7 February but not before he had concluded a contract to write a new opera for the next season. This contract signed with Pasquale Bondini the director of Count Nostitz’s National Theater led to the composition of his first opera for Prague Don Giovanni (K. 527). Ever since its première on 29 October 1787 the opera has moved audiences over andover again and has occupied a special position in Mozart’s rich and variegated output for the stage.Urtext of the New Mozart EditionFull score (BA4550-01) vocal score (BA4550-90) study score format 22.5 x 16.5cm (TP279) available for salePerformance material (BA4550-72) available for hire
