148), is a chamber work for two violins and viola by the Czech composer Antonín Dvořák, published in 1887.
Josef Kruis was a chemistry student who rented a room in the same house where the Dvořák family lived; he was taking violin lessons from Jan Pelikán, who was a member of the National Theatre Orchestra.
[1][2] The music proved to be too difficult for Josef Kruis, so Dvořák wrote an easier work for the same instruments, now known as Miniatures (in Czech: Drobnosti), Op.
The fourth movement, initially marked Poco adagio, is a theme and ten short variations.
The tempo is Molto allegro for the simple, rapid rhythms of the last two variations which conclude the work.
