Around the middle of the 18th century, plein-air music for wind instruments, known as Harmoniemusik, became popular at Austrian courts. The ensembles performing it were called Harmonie. They included from 5 to 8, and later – as this practice gained popularity – more instruments. Well-known and popular works were arranged for such ensembles. In the final concert of the 11th Sinfonia Varsovia Academy, young musicians and their professors will perform contemporary arrangements of two Beethoven symphonies, and Mozart’s original Harmoniemusik for 8 instruments as a point of interest. Its fragments became the basis for a later masterpiece, the Gran Partita. The performance will be led by the Berlin Philharmonic oboist and conductor, Andreas Wittmann.
