This is one of several of Dvořak’s Slavonic Dances that have been arranged by Patrick Clements for wind octet with optional double bass. The performance is computer-generated. The sheet music is freely-available on IMSLP and other arrangements by Patrick Clements can be found via his IMSLP page or his website.
The confusion over numbering arises from the fact that the original edition of the piano duets (from which the arrangement was made) had this as no.6 but nos.3 & 6 were later interchanged.
