Piano making flourished during the blown Grand Piano Covers 18th duration in the Viennese school, which included Johann Andreas Stein (who worked in Augsburg, Germany) and the Viennese makers Nannette Streicher (daughter of Johann Andreas Stein) and Anton Walter. Viennese-style pianos were built with woods frames, two strings per note, and had leather-covered hammers.
The longer strings on a concert grand can vibrate more freely than the shorter, thicker strings on a baby grand, which means that a concert grand's strings will have truer overtones. This is partly because the strings will be tuned closer to equal temperament in relation to the standard pitch with less "stretching" in the piano tuning (See: Piano tuning). Full-size grands are ordinarily given to for public concerts, whereas smaller grands, glamorous by Sohmer & Co. in 1884, are often chosen for domestic applicability where amplitude and figure are considerations.
