Dr. Diercks taught piano at the College of Wooster (1950–54), then began a long tenure at Hollins University, teaching theory and composition. He served as department chair from 1962 until 1990.
Much of Diercks' music is influenced by exoticism, including microtonality and "unconventional" musical sounds. An early work, Cave Music for vocalise and three players on prepared piano, accompanied a dance performed in Virginia's Dixie Caverns and broadcast on NBC-TV's Today Show.
His Twelve Sonatinas, performed by pianist Marthanne Verbit, are in the catalog of Albany Records. In 2009 The Guild of Carillonneurs in North America published his Fugue in C (for Elizabeth Graves Vitu) and Fantasia (commissioned by the University of Iowa-Ames).
Over 125 of Diercks' music has been published, for piano, voice, choral, chamber ensemble, and carillon. He has written more than two hundred reviews and articles in newspapers and journals, and authored two chapters published in the Denes Agay book "Teaching Piano".
Diercks lived in Honolulu, and served as president of the Hawaii Music Teachers Association from 1992 to 1996. Since then he has composed/arranged extensively for the Oahu Piano Quartet, and continued to compose for the carillon.
John Diercks died in April 2020 at ninety-two years old.[1]
