The Millennium III action
The Millennium III Action is made from ABS-Carbon, a strong and lightweight composite combining carbon fiber with ABS Styran.
This durable material allows for lighter action parts without losing strength, resulting in a faster, more powerful, and more stable performance than traditional all-wood actions.

Longer keys
Longer keys make playing easier and ensure a consistent feel across the entire surface.
Their taller profile and concert-length buttons add rigidity, allowing for better energy transfer and power.

Tapered, solid spruce soundboard
The soundboard is vital for a piano, converting string vibrations into a rich sound. Kawai uses high-quality, straight-grained, quarter-sawn solid spruce for the GL series soundboards. Each soundboard is carefully tapered to ensure the right resonance in different areas. Only those that meet Kawai’s strict quality standards are used in the GL series grand pianos.

Soft-closing fallboard
While the entry-level model in the grand piano range, this grand also benefits from a soft-closing lid or fallboard. A luxurious feature previously only high end instruments, which means no more trapped fingers!

Quality control and bespoke setup
With a fantastic build and component quality, beautifully set up by Kawai’s technicians before delivery, it is ready for a lifetime of service.
