The touch of grand pianos and that of upright pianos are fundamentally different. For example, a grand piano action allows fast repetition due to the horizontal direction of its mechanism. Such repetition did not used to be possible in upright pianos with common piano actions. However since 2007, Steingraeber & Söhne has been offering a ‘grand-piano’ feeling with fast repetition as a feature in its upright pianos. Four years of development led to the innovative Steingraeber-Ferro-Magnet (SFM) Action®.
