Braces

Radiating braces solidify the piano’s structure. Their triangular layout provides more support than parallel designs. This rigid system improves tuning stability and soundboard crown retention, and lengthens piano life. 3 braces.

Scale

Overstrung; combination of agraffe, with front and rear duplex. Rescaled bass and treble for lower tension scale for increased sustain, better tone clarity, and deeper clearer bass. 17,445 kg (38,460 lb) tension.

Ribs

Made from durable spruce to assure strong and constant support of the strings bearing down on the soundboard. Ribs are fully let-in to the inner rim to support the important soundboard crown and prevent the piano from losing its tone. Number of ribs: 11

Premium wool topfelt over premium wool underfelt. Weight of topfelt: 9.5 kg (20.9 lb). Compression-wired to retain permanent shape. Mahogany moldings. Tapered hornbeam hammershanks. Computer-designed pear-shaped hammers with reinforced shoulders result in superior tone, increased durability and greater voicing ability.

The fine synthetic ivory of the white keys has the same properties of friction, porosity, conductivity, and appearance as ivory.
