Walther Hermann Vetter (10 May 1891 – 1 April 1967) was a German musicologist. From 1946 to 1958, he was professor at the Humboldt University of Berlin.

Life Born in Berlin, Vetter, Lutheran, was the son of the Kapellmeister Johannes Vetter (1860–1928), a founding member of the Berlin Philharmonic. In 1897 the family moved to Greiz in the Principality of Reuss-Greiz (today: Thuringia), where the father founded an orchestra. Vetter first attended the and then, until the Abitur, the Latina (Old school) of the Francke Foundations in Halle an der Saale. From 1910, he studied musicology, art history and philosophy at the Martin Luther University of Halle-Wittenberg and conducting at the Leipzig Conservatory (with Hans Sitt, Stephan Krehl and Richard Hofmann). In 1914 he passed the conducting examination. During World War I, he served in an army music corps (1914/15) and as an army soldier among others at Hartmannswillerkopf and before Verdun on the Western Front (1915–1918).

He then continued his studies of musicology at the University of Halle. He also studied art history (with Wilhelm Waetzoldt) as well as philosophy and psychology (with Theodor Ziehen and Felix Krueger). From his academic teacher Hermann Abert, he received inspiration for his later research work, which ranged from music of ancient Greece to the composers of the 19th century. In 1920 he was awarded a Dr. phil. at the University of Leipzig with the dissertation Die Arie bei Christoph Willibald Gluck. After his studies, Vetter worked briefly as a music critic for the Hallische Zeitung, in 1921 he changed to a teacher at an adult education centre, music editor of the and music advisor to the Senate of the Free City of Danzig. In 1927, he received his habilitation from Max Schneider with the thesis Über Ausgewählte Kapitel aus der Entwicklungsgeschichte und Ästhetik des ein- und mehrstimmigen deutschen Kunstliedes im 17. Jahrhundert at the University of Breslau for Musicology and then received a private lectureship there. In 1928 he was appointed professor and provisional director of the musicological institute in Halle. From 1929, he was lecturer at the University of Hamburg.

Although he initially continued to work after the Machtergreifung by the Nazis, his re-habilitation attempt to Hamburg in 1934 was unsuccessful.Peter Petersen: Musicology in Hamburg 1933 to 1945.

Already in December 1933 he publicly admitted his leaning to the Nazis, although he never became a NSDAP party member. The musicologist Hans Huchzermeyer (2012) criticised Vetter for his "National Socialist and anti-Jewish statements" during the Nazi era. His lecture on Folk characteristics in Mozart's operas from 1938 can be taken as an example.Annkatrin Dahm: The Topos of the Jews.
