Lyre Piano by Schleib, J

From about 1825 on, Schleip built it, as here, with pedals. Finally, in about 1832 he began building heavier instruments with hanging actions. Its three pedals are for una corda, bassoon effect, and release of the dampers. A technical particularity of the instrument is that the sound board is suspended only on the right side so that its left side can vibrate freely like a tuning fork. To balance the volume between bass and treble and to prevent the bass from becoming too dull, the bass side of the sound board is spared. Finally, to further the harmony and beauty of the sound, the strings, the grain of the sound board, and the beams of the supporting structure run parallel to each other at the same angle.
