Field became well-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 18 nocturnes and associated pieces such as "Andante inedit", H 64. 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. These pieces were admired by Frédéric Chopin, who subsequently made the piano nocturne famous, and Franz Liszt, who published an edition of the nocturnes based on rare Russian sources that incorporated late revisions by Field. Liszt's preface to the said edition was an extensive eulogy for Field and his nocturnes.
