A soundboard is the surface of a string instrument that the strings vibrate against. In a grand piano, the sound board is a large horizontal plate at the bottom of the case.
The instrument is reportedly resistant to temperature change and has greater resonance, vibration and sustaining power than a conventional model.
Bogányi reportedly aimed for a human, warm, sound, similar to his experience of playing Liszt’s own piano.
‘My goal was not to make it better, but to take a different approach,' he said. 'The sound is more powerful, more straightforward, without being aggressive. The result is a completely new experience.’
