The grand piano lid plays a significant role in the sound when its surface and mass are effectively integrated into the sound by 'Lifsound'.

This seminar will introduce the patented 'LifSound' grand piano lid membrane bridge in terms of its construction and operation. Comparative sound examples in various positions of the grand piano lid will demonstrate the differences in sound with and without 'Lifsound'. It will also be shown how a new sound dimension can be opened up using simple means, not only for grand pianos, but also for pianos, harpsichords and clavichords, by allowing the instrument casing to resonate more freely.
