Porpora 3 Concerti facili

The source of this publication was issued in London in 1745 by John
Walsh Jr. Walsh's publication contains six four-movement works,
originally written for violin, solo cello, a keyboard instrument and a
second cello to reinforce the bass of the latter, but the role of the
violin is insignificant, so these works can be regarded as pieces for
cello. Of the six works, the arranger of the volume was publishing the
three most suitable ones to that as cello concertos; the piano part
incorporates both the violin interludes and the continuo. In the cello
part higher positions do occur, but they do not necessarily require
use of the thumb; they are playable after 4-5 years' intensive study
of the instrument.
