Roberta Bitgood was born in New London, Connecticut, of parents Grace Robinson Prentis and Robert A.T. Bitgood. She showed an early talent for music and started violin lessons at the age five. She studied at the Williams Memorial Institute from 1920–24 and began performing in local churches and school orchestras. Bitgood graduated from the Connecticut College for Women and continued her studies in New York at the Guilmant Organ School with William C. Carl, where she graduated in 1930. She went on to receive a master's degree in music education from Teacher's College at Columbia University in 1932 and a master's and doctoral degree in sacred music from Union Theological Seminary after studying with Clarence Dickinson and David Williams in 1935 and 1945.
