The very first STEINWAY & SONS patent was granted in 1857, and since that time the company has been granted more than 150 additional patents, positioning the STEINWAY as the piano by which all others are judged. Our latest innovation, the STEINWAY & SONS SPIRIO, is the world’s finest high resolution player piano. A masterpiece of craftsmanship, technology and artistry, SPIRIO provides an unrivaled musical experience, indistinguishable from a live performance.
