The String Sextet for String Orchestra, H 224 A, is an arrangement of the original String Sextet for two violins, two violas, and two violoncellos, H 224, from 1932. After World War II, American Music Publishers (AMP) in New York expressed a desire to add a double bass part to the original Sextet. Martinů accepted the offer, and later adapted the Sextet’s score. The resulting composition’s string orchestra version, still richer in sound, was first performed in 1951 in Louisville, USA, and was conducted by Robert Whitney.
