Delta Omicron (ΔΟ) is a co-ed international professional music honors fraternity whose mission is to promote and support excellence in music and musicianship.
Delta Omicron International Music Fraternity was founded on September 6, 1909 at the Cincinnati Conservatory of Music by three undergraduate students: Hazel Wilson, Lorena Creamer, and Mabel Dunn.:3 Additional charter members included Mae Chenoweth, Grace Hudson, and Adah H. Appell.:3  The Articles of Incorporation were signed by the charter members on December 8, 1909 and filed in the office of the Secretary of State of Ohio. The charter was granted on December 13, 1909. In 1923, this date was established as "Founders Day" since not all collegiate institutions at which chapters were installed had opened for the fall semester by September 6.
Originally called "Delta Omicron Sorority," the organization changed its name to "Delta Omicron Fraternity" in 1947 since "fraternity" was the preferred name in Panhellenic circles.:21 The fraternity has collegiate chapters established throughout the United States. Several chapters were established abroad, but are currently inactive. Delta Omicron is the only organization of its kind, since it was founded by students for students and is also the only professional music fraternity founded by underclassmen. Originally an all-female organization, Delta Omicron first initiated men in 1979 after changing the bylaws to admit men in 1977.:35
Delta Omicron Foundation, Inc.
The Delta Omicron Foundation, Inc. was founded on June 17, 1958. and is chartered in Ohio as a nonprofit organization. The Foundation was granted tax-exempt status on March 27, 1964. The Foundation administers the philanthropies of Delta Omicron as a separate corporation. It supports and promotes music and musicians through educational grants and scholarships for music study, the commission of composers, awards for musical accomplishments, subsidies for publications and programs promoting music, and national and international music endeavors. It also supplements Delta Omicron's endowment fund, which was established in 1927.
Chapter and membership information
Membership is determined on the basis of talent, scholarship, and character and is open to collegiate music students enrolled in schools where Delta Omicron chapters are located, to music faculty members in those schools, and to professional musicians. Over 28,000 members have been initiated. The first honorary memberships were offered to women musicians of "national reputation" in 1916.:6
Collegiate chapters are chartered in accredited institutions of higher learning and derive their names from the Greek alphabet in the regular sequence according to the date of installation. A member affiliated with a collegiate chapter (either undergraduate or graduate) must be a music major, music minor, or the equivalent of a music minor (as determined by individual chapters).
Alumni chapters derive their names by using the name of the nearest collegiate chapter prefixed by the letter Zeta. Alumni chapters adopted Greek letter names beginning in 1944.
Delta Omicron was the first music fraternity to establish chapters abroad. International chapters of Delta Omicron are those that are established outside of the boundaries of the United States, the first of which was established in South Korea on June 7, 1958. Members of an international chapter may be made up of collegiate or alumni members. International collegiate chapters derive their names from the Greek alphabet, prefixed by the letter Kappa.
Delta Omicron has a total of 183 chapters and clubs. Of the 129 collegiate chapters that have been established in the United States, 37 are active. Of the 46 alumni chapters and clubs that have been established in the United States, 15 are active.
Eight chapters - seven collegiate and one alumni - were established in South Korea, due largely to the work of Lenore Harpster Lutz, who traveled to the country with her husband, a missionary. All are currently inactive.

The journal began publication with volume 1 in June 1915.:5 The Wheel was published annually from 1915 to 1923, semiannually 1924 to 1925, triennially 1926 to 1929, and quarterly since 1930.:13, 117, 118 The editor seeks articles on information related to the fraternity, its members and patrons, collegiate and alumni chapters, special events, awards, and music-related articles of interests to musicians.
