His works were mostly published as collections of short pieces, with the exception of the Concerti and Sonatas. They are often grouped by category, as follows:
* [[Études (Chopin)|Etudes]] - two sets of technical studies for piano that to this day are regarded as a watershed in the progress of any pianist. Unlike those of previous composers such as Czerny and Cramer, Chopin's etudes combine technical difficulty with musical expression, thus helping to popularize the form.
* Nocturnes - slow, dreamlike pieces. The form was originally pioneered by the Irish composer [[John Field]].
* Mazurkas - an adaptation of a native Polish dance form. These miniatures often show Chopin at his most harmonically adventurous.
