Editing String trio (section)

== Later history ==
During the mid to late 18th century, a couple of developments occurred in the genre. The changes included the absence of a [[figured bass]], the equal treatment of all voices (as opposed to the top voice dominating the musical texture), and the use of [[sonata form]] in the first movement.<ref name=":2" /> These early developments paved the way for the genre to further expand into four specific types: the grand trio, the concertant trio, the brilliant trio, and the Hausmusik trio.<ref name=":2" />

=== Grand trio ===
The grand trio was a product of South Germany and Austria. It was modeled after the mid to late 18th century [[serenade]] and [[nocturne]].<ref name=":2" /> One of the best-known examples that legitimized the grand trio is Mozart’s [[Divertimento for String Trio (Mozart)|Divertimento in E-flat]], K. 563. Inspired by the piece, [[Ludwig van Beethoven|Beethoven]] set out to write [[String Trio, Op. 3 (Beethoven)|String Trio in E-flat, Op. 3.]]<ref name=":2" />

=== Concertant trio ===
The concertant trio was created in France, consists of two movements, and all three voices are used equally in the texture. The first movement is usually in [[Binary form|binary]] or sonata form. [[Giuseppe Cambini]] was the leading composer of the genre.<ref name=":2" /> Some of his works include ''3 trios concertants pour violon alto et violoncelle'', Op. 2 and ''6 trios concertants pour Deux Violons et Basse'', Op. 18.

=== Brilliant trio ===
The brilliant trio became the most popular string trio in France in the 19th century due to its virtuosic passages featured in the first violin part.<ref name=":2" /> The trio consists of three movements, organized in a fast-slow-fast pattern, and the first movement is written in sonata form. The first composer to use "brilliant" in the genre was Rudolph Kreutzer in his pieces ''3 Trios brillants'', Op. 15 and Op. 16.<ref name=":2" />

=== Hausmusik trio ===
The Hausmusik trio was intended for amateurs and student musicians. It was regarded as a pedagogical tool intended as preparation for the grand trio, the brilliant trio, and the [[string quartet]].<ref name=":2" /> Some examples of the Hausmusik trio include ''6 Trios progressives'', Op. 28 by [[Franz Anton Hoffmeister]] and ''3 Trios faciles et progressives'', Op. 43 by Franz Alexander Pössinger.
