He appears, however, to have known but little of the capabilities of
the instrument, which seemed to him coarse and inexpressive beside his
favorite clavichord. Stein appears to have made use of the "una corda"
shift. Probably by knee-pedals, subsequently by foot-pedals, the
following effects were added to the Stein pianos.
The harpsichord "harp"-stop, which muted one string of each note by
a piece of leather, became, by the interposition of a piece of cloth
between the hammer and the strings, the piano, harp, or _celeste_. The
more complete sourdine, which muted all the strings by contact of a long
strip of leather, acted as the staccato, pizzicato, or pianissimo. The
Germans further displayed that ingenuity in fancy stops Mersenne had
attributed to them in harpsichords more than a hundred and fifty years
before, by a bassoon pedal, a card which by a rotatory half-cylinder
just impinging upon the strings produced a reedy twang; also by pedals
for triangle, cymbals, bells, and tambourine, the last drumming on the
sound-board itself.
Several of these contrivances may be seen in a six-pedal grand
pianoforte belonging to Her Majesty the Queen, at Windsor Castle,
bearing the name as maker of Stein's daughter, Nannette, who was a
friend of Beethoven.
