The ST-1 Institutional Piano is a powerhouse performer for institutional settings. Its exclusive Millennium III Upright Action features ABS-Carbon parts that are incredibly strong and lightweight — properties that allowed our engineers to optimize speed, repetition, power and control. Its five sturdy back posts measure 80mm x 80mm for maximum rigidity and stable tuning.
The 47″ raised music rest is the longest on any institutional piano — perfect for sheet music that extends laterally. Longer keys provide more consistent touch response. A stylish reinforced bench is made to last longer than conventional benches. And its “Soft Fall” Fallboard closing system protects hands and the piano’s finish from the harm that jarring close might cause. With all these valuable attributes and many more, the ST-1 is the ultimate blend of performance and durability.

This is the first piano I’ve ever bought myself. The sound is lovely; warm without too much brightness. The cabinet is beautiful. So excited to spend years with it.
