Ivan Lipaev played trombone in Russia's first brass quartet starting in around 1888, and in the Bolshoi Theatre orchestra from 1893 to 1912 and from 1924–31. He was also dedicated to the modernization of music pedagogy in the Russian empire and advocated for better conditions for music students and orchestra members. He was made Honored Artist of the RSFSR in 1925.
Lipaev was also interested in Jewish music, was a friend of pioneering ethnomusicologist Joel Engel, and published what may have been the first scholarly examination of Klezmer music in a 1904 issue of Russkaya muzykal'naya gazeta.
