The Model M grand piano is our medium-sized baby grand. This makes it the perfect instrument for private homes as well as for budding pianists at music schools. Anyone who plays it will be thrilled by its sensitive mechanics and the unmistakable Steinway sound. Our Model M grand piano is accompanied by the slightly longer O-180, as well as the smallest grand piano from Steinway & Sons, the S-155. All three baby grands feature the same design, mechanics and keyboard.
