SPIRIO, a handcrafted STEINWAY like all others, is the next step in STEINWAY'S history of ceaseless improvement in its mission — declared by Henry E. Steinway, "to build the best piano possible" — and brings the unparalleled craftsmanship of the STEINWAY piano to your home coupled with cutting-edge technology and the peerless musicality of STEINWAY ARTISTS.

The STEINWAY & SONS SPIRIO is the world’s finest high resolution player piano. A masterpiece of artistry and engineering in your home, SPIRIO enables you to enjoy performances captured by great pianists — played with such nuance, power and passion that it is utterly indistinguishable from a live performance.

The STEINWAY SPIRIO remains a fully-functioning STEINWAY & SONS piano, with the same level of painstaking craftsmanship that goes into every single instrument STEINWAY produces. STEINWAY craftsmen seamlessly install SPIRIO at the time of the piano's manufacture, ensuring no alteration in the exterior beauty or performance you expect from STEINWAY. 

SPIRIO'S high resolution playback system uses propreitary software to measure hammer velocity (up to 1020 dynamic levels at a rate of up to 800 samples per second) and proportional pedaling - for both the damper pedal and soft pedal (up to 256 pedal positions at a rate of up to 100 samples per second). The Steinway & Sons Spirio player piano reveals the subtlety and passion of an artist’s original performance. Soft trills, delicate pedaling, and thundering fortissimos present no difficulty for Spirio and are reproduced with unparalleled accuracy, smoothly and precisely realising the pianist’s entire range of motion and emotion.

The powerful STEINWAY sound, the ever-expanding content library and high resolution technology are all easily accessible thorugh the STEINWAY SPIRIO app - an intuitive and easy-to-use interface.

A cast iron treble bell, affixed to rim's underside at treble bend, holds plate firmly in position by means of a steel bolt. The STEINWAY & SONS iron wedge anchors brace ends securely to crossblock assuring permanent rim posture.
