The Symphony No. 6 ("Fantaisies symphoniques"), H. 343, by Bohuslav Martinů was begun in New York City in 1951, after a hiatus of four years since its predecessor, and was tentatively completed three years later on 23 April 1953. In Paris, in the months following its completion, Martinů undertook some revisions to the score. It is dedicated to Charles Munch, on the occasion of the 75th anniversary of the Boston Symphony Orchestra, who premiered the symphony on 7 January 1955 (Llade 2009, 61). Martinů originally called the work Fantaisies symphoniques, and this is sometimes regarded as its only correct title (Evans 1960, 25).
