TRADITION AND TECHNOLOGY ARE INDISPENSABLE ELEMENTS OF PIANO TONE. TRADITION LAYS THE FOUNDATION FOR OUR DISTINCTIVE TONAL CHARACTER, TECHNOLOGY EMPOWERS IT WITH LIFE, BREADTH, AND DEPTH THAT LASTS FROM GENERATION TO GENERATION.

CORE is an acronym that stands for "Convergence for Optimum Reflected Energy." Convergence refers to the way the piano's strength centers – the rim, plate and underside beams – all focus on one central point at the heart of the instrument. This focus creates an incredibly strong "core" foundation that maximizes the reflective capabilities of the inner rim for outstanding tonal power and sustain. (GL40 and GL50 Only)

The soundboard is the heart of a piano's tone. Kawai uses only straight-grained, quarter-sawn solid spruce for GL Series soundboards. Each one is strategically tapered to provide the proper degree of resonant movement in each region. Only soundboards that exceed our demanding resonance standards are selected for use in the GL Series grand pianos.
| |||||||||||||
Bridges transfer the vibrations of the
strings to the soundboard. GL Series
bridges are made of solid maple or beech
and are carefully set and matched to the
iron plate for correct string pressure and
optimal tonal transfer.
| |||||||||||||
GL Series hammers are constructed
with maple mouldings, premium wool
felt, and a layer of dense underfelt all
working in harmony to produce the rich,
expressive tone that is a hallmark of
Kawai grand pianos.

Dual Duplex Scaling is an important design element that helps to make possible the beautiful singing quality of the GL Series grand pianos. Duplex Scaling allows the extreme ends of the piano’s strings to vibrate and produce harmonics that enhance tone. Dual Duplex design combines a front duplex region (between the tuning pins and agraffes) with a similar rear duplex region (between the aliquots and the bridge) to add a double measure of harmonic richness, brilliance, complexity and sustain to the piano’s tone.
