Pronouncing Dictionary of Music and MusiciansPronouncing the titles of classical music and the names of composers and performers is a daunting task for many Americans because so many of the words are foreign to us. Adding to the difficulty is the fact that some of the names that look familiar are not pronounced as we would pronounce them. This dictionary provides some help in the form of pronunciations by a phonetic system devised by E. Douglas Brown of the staff of WOI Radio at Iowa State University. Many of the pronunciations in the dictionary were derived from tape-recorded pronunciations made by foreign nationals who were speaking their respective native languages. Prepared primarily for the announcing staff of WOI, the dictionary has been found useful by them and is being made freely available to others who may find it of value. Although imperfect and far from complete, the dictionary, with its 30,000 entries, is the most extensive of its type now available.
