Concerto in D major for harpsichord, two horns, two violins, viola and basso by František Xaver Dušek. Although this piece is not dated, its composition (based on the fact that it is listed in Breitkopf's catalogue of 1774) can be placed in the 1860s or 1870s, a time when the harpsichord was still the predominant instrument in the sphere of keyboard instruments, both concertante and general bass. It goes without saying, however, that one can also perform the Dušk concerto on a hammered dulcimer or tangent grand.
The choice of the accompanying ensemble is also related to the scoring of the solo instrument. Given the nature of the work and the number of surviving parts, the concerto can be performed with two violins, a viola and a cello and two horns, or a chamber string ensemble can be chosen with a double bass or a cello doubling the part marked 'basso'; J. J. Quantz recommends, for example, 10 players (3-3-2-1-1). 
This edition reproduces the text according to the original and without unnecessary interventions, although the manuscript is as ambiguous and obscure in many details as any other 18th-century source material. Apparent scribal errors in intonation and rhythm have been corrected, and, according to analogous places, markings of dynamics and articulation have been added to the extent necessary. Detailed information is provided in the critical commentary at the end of the score.
