Thomas Koschat (1845–1914) österreichischer Komponist, Chorleiter und Schriftsteller - Eigenhändiges signiertes Albumblatt mit Noten seines Welterfolgs „Verlassen, verlassen, verlassen - 1896

Thomas Koschat was an Austrian composer, choir conductor, and writer active in the late 19th and early 20th centuries, known notably for his folk-inspired vocal music. His compositions often drew on the traditions of Carinthia, his native region, blending lyrical melodies with choral arrangements that remain a part of regional classical music heritage. The piece "Verlassen, verlassen, verlassen" (meaning "Abandoned, abandoned, abandoned") achieved international recognition during his lifetime as a poignant example of sentimental and dramatic vocal music. An autograph album leaf featuring handwritten musical notation from this celebrated work not only captures a piece of musical history but also offers insight into Koschat's compositional style and the performance practices of his era. Collectors and enthusiasts of classical vocal music, particularly of Austro-Germanic Romantic traditions, prize such documents for their cultural and historic significance.
