Leichtentritt was a dedicated and intense musicologist. For his huge piece of writing
Geschichte der Motette (1908), he analysed over 600 motets in manuscripts. His writings on Handel (1924) discuss a wide range of Handel's works, including unperformed operas and
oratorios.
Geschichte der Musik (1909) summarized the history of Western music in an easy and approachable manner. Edward Dent called his
Ferruccio Busoni (1916), "a useful outline and a concise guide to his works". Two of Leichtentritt's works were more famous than any of his others:
Music, History, and Ideas (1938) and
Music of the Western Nations (1956).
Music, History, and Ideas, which drew from his time lecturing at Harvard, analyzes music as a category of culture, comparing it to other arts, politics, philosophy, and religion.
Music of the Western Nations connects music to the culture and sociopolitical climate of Western countries.
