USED 1889 Steinway K-52 Vertical MS | 65515

The Steinway & Sons K-52 is a 52-inch professional upright piano, widely regarded as one of the finest vertical pianos ever made. The K-52 features a generously sized diaphragm soundboard that rivals—and in some cases exceeds—the soundboard area of many baby grand pianos. This design delivers a full, resonant tone with rich harmonics and grand-like depth in the bass, all within a vertical format that fits beautifully in homes, studios, and performance spaces. Known for its unmatched craftsmanship, expressive dynamic range, and enduring quality, the K-52 remains a benchmark for upright piano performance worldwide.
