Influences

By the time of Chopin's birth in 1810, John Field was already an accomplished composer. Eventually, the young Chopin became a great admirer of Field, taking some influence from the Irish composer's playing and composing technique. Chopin had composed five of his nocturnes before meeting Field for the first time.

In his youth, Chopin was often told that he sounded like Field, who in turn was later described as sounding "Chopinesque". The composer Friedrich Kalkbrenner, one of Chopin's early influences, once inquired as to whether Chopin was a student of Field. While Chopin held Field in high respect and considered him one of his primary influences, Field had a rather negative view of Chopin's work. Upon meeting Chopin and hearing his nocturnes in 1832, Field is said to have described the composer as a "sickroom talent". Nonetheless, Chopin still admired Field and his work and continued to take inspiration throughout his life.

Chopin's nocturnes carry many similarities with those of Field while at the same time retaining a distinct, unique sound of their own. One aspect of the nocturne that Chopin continued from Field is the use of a song-like melody in the right hand. This is one of the most if not the most important features to the nocturne as a whole. The use of the melody as vocals bestowed a greater emotional depth to the piece, drawing the listener in to a greater extent. Along with the right-hand melody, Chopin continued the use of another nocturne "necessity", that of playing broken chords on the left hand to act as the rhythm under his right-handed "vocal" melody. Another technique used by Field and continued by Chopin was the more extensive use of the pedal. By using the pedal more, the music gains more emotional expression through sustained notes, giving the piece an aura of drama. With these main attributes of the "Field nocturne" Chopin was inspired, and expanded upon them to develop the "Chopin nocturne".

One of the greatest innovations made by Chopin to the nocturne was his use of a more freely flowing rhythm, a technique based on the classical music style. Also, Chopin further developed the structure of the nocturne, taking inspiration from the Italian and French opera arias, as well as the sonata form. Composer Franz Liszt even insisted that Chopin's nocturnes were influenced by Vincenzo Bellini 's bel canto arias, a statement affirmed and echoed by many in the music world. A further innovation of Chopin's was his use of counterpoint to create tension in the nocturnes, a method that even further expanded the dramatic tone and feel of the piece itself. It was mainly through these themes of operatic influence, freer rhythms, and an expansion into more complex structures and melodic playing that Chopin made his mark on the nocturne. Many think of the "Chopin nocturne" as a mix between the form and structure of Field and the sound of Mozart, displaying a classic / romantic -influenced theme within the music.
