Alteration and transformation, influence and interaction! The horn and the piano have gone through immense changes over the course of time, as this recording with works by Beethoven, Schumann and Klebe intends to illustrate. The natural horn, the Romantic valve horn and the modern horn enter in dialogue with the fortepiano, the Romantic piano and the modern grand. On this , Premysl Vojta and Tobias Koch have embarked on an adventurous musical expedition in the recording studio by dealing with three different types of horns and three different keyboard instruments in the course of three days, thereby attempting to span a wide musical range that depicts the transformation of the historical timbre ideal, condensed as a time lapse. The duo's intention is to show how the language of musical composition itself has undergone profound change on the basis of certain instrumental modifications. The distance covered is immense from Beethoven's Horn Sonata, still entirely immersed in the style of the late 18th century, passing through Robert Schumann's Romantic attitude and leading to Giselher Klebe's Alteration of Beethoven's so-called Moonlight Sonata, thereby creating a technically challenging work with perspectives that mirror a multitude of tendencies. It is no coincidence that this programme, in so doing, returns to Beethoven, albeit experienced in a very different way in Klebe's work, innovative, revolutionary elements of composition and instrumental technique are directly noticeable.
