Feld was born into a musical family, his father a well-known professor of violin at the Prague Conservatory which followed the tradition of Otakar Ševčík, the master of Jan Kubelík.
His teaching has also taken him to positions at other American universities as well as ones in Denmark, Norway, Germany, France, England, and 1991 in Japan.
The American musicologist, Dr Lana Kay Johns (her annotated bibliography),[2] has counted more than two hundred titles (a cataloging system referred to here as J).
It includes compositions from an opera for children (The Postman's Tale, 1956) to partitions with full scores for orchestra, as well as the cantata Cosmae Chronica Boemorum, 1988) in the tradition of Dvořák on a medieval text.
Feld forged aesthetic guidelines during more than half a century of activity and admitted having initially felt close to Martinů, but even more to the French school of Debussy to Messiaen, including Honegger.
