Royal Philharmonic Orchestra - Meditation from Thais

Erard in France approx. 1810. It is a large wooden frame of a triangular shape with a curved upper side, inside which strings of different lengths and settings are vertically stretched. At one end, they are fixed on the deck (the flat upper part of the resonator body), the other are wound on pegs in the upper (curved) part of the instrument, which also carries the pedal discs. A system of levers placed in a column (on the opposite side to the performer side A. ) connects the latter with pedals mounted in a tree. pedestal base. Each of the pedals, moving in three positions, drives the wheels. They shorten the working length of the string so that its sound is increased by half a ton (when you press the pedal to half) or by a tone (when you fully press the pedal). 7 pedals - according to the number of steps diatonic. scales - affect the same. strings of the scale A. at the same time in all its octaves. This allows you to rebuild A. in all major and minor keys.
