She was concertmistress for the U.S. tour of the Ballet Russe de Monte Carlo during World War II, reprising that position for the original Broadway production of Brigadoon in 1947.

In 1944 she began a successful radio career at New York classical station WQXR, writing and producing more than 200 episodes of her own performance-interview program "Notes and Quotes" on Sunday afternoons and appearing as soloist and concertmistress of the Stromberg-Carlson string orchestra.

Her annual Town Hall recital in 1956 elicited this commentary in The New York Times: "Miss Field is a rare combination, an extremely facile technician who also comprehends that the task of the performer is to make music rather than to set a new record for the track.

It is true that in bravura playing Miss Field is by no means found wanting; but mere technique is never allowed to get in the way of the music.

"[12] Field performed and recorded extensively in Europe during the 1950s and early 1960s, notably with expatriate American conductor Dean Dixon.

Her instrument during those years was a 1698 "long pattern" Stradivarius once owned by Joseph Joachim[13][14] She also appeared as piano accompanist with string player colleagues.
