[1] An orquesta típica is an expanded version of a sexteto típico, which includes 2 bandoneons, 2 violins, double bass and piano.
One of the earliest, Orquesta Flor de Cuba, had the following make-up: cornet, trombone, figle (ophicleide), two clarinets, two violins, double bass, kettle drum, and güiro.
The ophicleide was a sort of bass bugle with keys, invented in 1817, now superseded by the tuba and/or baritone horn, the name surviving for a pipe organ stop; the trombone would be more typically a valved rather than a slide instrument.
In the early 20th century, there were still several popular orquestas típicas, such as those directed by Enrique Peña and Félix González.
[2] Charangas would become, along with son conjuntos and Cuban-style big bands, one of the main precursors of the salsa ensemble, which is characterized by the inclusion of multiple trombones.
