Richard Strauss, „The great representative of his time" played a decisive role in the evolution of the horn, both as a solo instrument and as an instrument of the orchestral ensemble. His famous symphonic poems abound in very difficult horn solos, and in Richard Strauss's orchestration the horn is an irreplaceable partner. The composer knew the instrument very well, with its possibilities, thanks to his father Franz Strauss, a famous horn player of the 19th century. R. Strauss’s concert horn works are the basis of the literature and are loved by professional horn players.
