To make a living Harold Samuel taught (he was, for example, the piano teacher of the British composers Benjamin Britten and Elizabeth Poston), did vocal coaching and became a sought-after accompanist (performing especially with violinist Isolde Menges). His solo career, however, was at a standstill until 1919 when he played an all-Bach programme in London. He soon found a ready audience for large amounts of Bach's keyboard works in their original form. In 1921 he gave six successive Bach recitals in London and a similar cycle in New York City. He toured the US regularly from 1924. He wrote a musical comedy, "Hon'ble Phil", songs and piano pieces.
