An upright grand piano, also known as a vertical grand piano, is a type of piano that is generally larger and taller than a traditional upright piano. It derives its name from the fact that its strings and soundboard are positioned vertically, similar to a grand piano, only turned on its side to fit against a wall. This design allows for a longer string length and improved sound quality compared to other upright pianos. However, the term “upright grand” is not a standard industry term and is more of a marketing term used to describe large upright pianos. Many experts in the field of piano manufacturing and repair do not recognize the term and instead classify these instruments as simply vertical pianos.
