The single action harp achieved great popularity throughout the rest of the 18th century as was evidenced in the French Court
by Marie Antoinette perhaps, the most famous player of this instrument.
The harps of this period were magnificently decorated with relief carving, lavishly gilded and hand painted.
Principal maker are Cousineau, Naderman, Erard, Pleyel, Chaillot, Louvet, Renault Chatelain...
As music evolved it was also necessary for the harp, if it was to maintain its popularity, to move with the times
it had become vitally important for the harp to be able to played in all keys.
As a result of this need, Sebastian Erard obtained a patent in 1810 for the Double Action pedal harp.
Erard redesigned the single action mechanism, replacing the crochets with two rotating pronged discs.
The strings, now each equipped with two discs, were able to produce a flat, natural and a sharp depending on the position of the corresponding pedal, allowing the harpist to play in every key.
