In 1883 Adler became lecturer in
musicology at University of Vienna, on where he wrote "Eine Studie zur Geschichte der Harmonie" (An Essay on the History of Harmony), published in
Sitzungsberichte der Philosophisch-Historischen Klasse der Wiener Academie der Wissenschaften, 1881. In 1884 he founded (with
Friedrich Chrysander and
Philipp Spitta) the
Vierteljahresschrift für Musikwissenschaft (Musicology Quarterly). Adler provided the first article of the first issue, "Umfang, Methode und Ziel der Musikwissenschaft" ("The Scope, Method, and Aim of Musicology", 1885), the first attempt at a comprehensive description of the study of music. It famously divides the discipline into two subdisciplines,
Historische Musikwissenschaft (historical musicology) and
Systematische Musikwissenschaft ("systematic musicology"). Systematic musicology included
Musikologie or
vergleichende Musikwissenschaft (comparative musicology), which later became an independent discipline (cf.
ethnomusicology). Although these subfields do not precisely conform to current practice, they are roughly maintained in modern European musicology and roughly correspond to the North American division of musicology into
music history (often called "musicology"),
music theory, and
ethnomusicology. In 1886, he published
Die Wiederholung und Nachahmung in der Mehrstimmigkeit; in 1888,
Ein Satz eines Unbekannten Beethovenischen Klavierkoncerts. In 1892-93 he edited a selection of musical compositions of the Emperors
Ferdinand III,
Leopold I, and
Joseph I. Between 1894 and 1938 he was editor of
Denkmäler der Tonkunst in Österreich, a seminal publication in music history. Adler was the first
music historian to emphasize style criticism in research. His attitudes and procedures are evident in the
Handbuch der Musikgeschichte (Handbook of Music History), of which he became editor in 1924. == National Socialist period ==
