Upright pianos are also known as vertical pianos, as they stand upright and have their strings and soundboard positioned vertically. These pianos are also referred to as console pianos, studio pianos, and spinet pianos, depending on their size and style. Console pianos are taller and more substantial, while studio pianos are smaller and designed for home use. Spinet pianos are the smallest of the upright pianos and were popular for their compact size and affordability in the mid-20th century. Despite their varied names, all upright pianos offer a classic and traditional sound and feel that has made them a favorite choice for piano enthusiasts and music lovers of all ages.
