The bulk of La mer was composed during a visit to Burgundy – a long way from the nearest sea – although the work was completed in the English seaside town of Eastbourne. The composer himself argued that his inspiration was drawn from a range of ocean view paintings and from literature in which the sea played a major part. Debussy described the work as 'Three symphonic sketches for orchestra' (Trois esquisses symphoniques pour orchestre), thus avoiding the term 'symphony', which would have imposed a specific musical structure, as well as the expression 'symphonic poem', which would imply that the music was descriptive in nature. 'Sketches' was a wise choice, precisely because it neatly conveys that the music is meant to do no more than provide an impression.
