- Quadro Viegas

- Duo Aurélie Guerreiro Viegas & Wim Brabants

Original chamber music with single-action harp (1770-1830)

The single-action harp in the style of Louis XVI has been manufactured in Paris from about 1760 to around 1820. Charles-Louis Favart reported already in 1761 that the new harp was very fashionable and that the ladies in Paris were almost mad to play it.
As it was the favorite instrument of Marie-Antoinette, interest in the harp increased in the Parisian nobility.

Many works for harp solo and harp combined with other instruments were written in this period, not only by well-known harpists such as Johann-Baptiste Krumpholtz (1742-1790) and François-Joseph Naderman (1781-1835), but also by other composers such as Louis Spohr (1784-1859) and Jan Ladislav Dussek (1760-1812), who’s wives were both gifted harp players.

For many years Wim Brabants has collected pieces for harp and flute as well as quartets and trios with harp from the period 1775-1830 in order to introduce this charming repertoire to the concert audience.
