Taylor was a promoter of classical music throughout his life. His journalism career included posts as music critic for the New York World beginning in 1921, and editor of Musical America from 1927 to 1929.
Taylor also worked extensively in broadcasting, as well as intermission commentator for the New York Philharmonic. He appeared in Walt Disney's 1940 film Fantasia as the film's Master of Ceremonies, and was instrumental in selecting the musical pieces that were used in the film, including the then-controversial Sacre du Printemps. In the long-unseen roadshow version of Fantasia, issued on DVD in 2000 and re-released on the 2010 Fantasia/Fantasia 2000 Blu-ray release, all of Taylor's voice-over work was re-recorded by veteran voice artist Corey Burton. The complete film was originally 124 minutes long, due almost entirely to the fact that Taylor's commentaries were more detailed in the roadshow version. But, the original audio elements for these longer commentaries had deteriorated to the point that they could no longer be used, so Corey Burton was selected to re-record all of the dialogue for consistency. The general release version of Fantasia, running 120 minutes, is the version most audiences are familiar with. In that version, Taylor's commentaries were severely abridged (bar the introduction to Toccata and Fugue in D Minor).
That same year, he served the same role as Master of Ceremonies for the classical portion of a "Carousel of American Music", a famous concert series held in San Francisco on September 24. The concert had Irving Berlin, George M. Cohan, Jerome Kern, Hoagy Carmichael, WC Handy, Johnny Mercer, and many more of America's top songwriting talents performing their own compositions. (The original release was titled "Cavalcade of American Music" and includes a performance of Taylor's own work "Circus Day".) The recording was added to the National Recording Registry in 2016.
He provided the commentary of the technical story behind the recording of actual cannon fire and carillon for the famous 1954 Mercury Records album, by Antal Dorati and the Minneapolis Symphony Orchestra, of Tchaikovsky's 1812 Overture – still one of the most highly regarded recordings of that piece, and the best-selling classical LP of the 1950s. Taylor also recorded commentary for other Mercury recordings: Benjamin Britten's The Young Person's Guide to the Orchestra, the 1958 stereophonic re-make of the 1812 Overture and Frederick Fennell's ground-breaking two-album "The Civil War," which featured original music played on period instruments and sound-montages, narrated by Taylor, of period weaponry and music.
