Irish composer John Field’s Nocturnes (1782–1837) for piano are known for being the first nocturnes ever written. Field became best known for his post-London style, probably developed in Moscow around 1807. The characteristic texture is that of a chromatically decorated melody over sonorous left hand parts supported by sensitive pedalling.
Field also had an affinity for ostinato patterns and pedal points, rather unusual for the prevailing styles of the day. Entirely representative of these traits are Field’s nocturnes. These works were some of the most influential music of the early Romantic period: they do not adhere to a strict formal scheme (such as the sonata form), and they create a mood without text or programme.
