Created as a space-saver, vertical pianos began as a grand piano turned up on end so the strings ran vertically instead of horizontally. Consequently, each vertical piano usually takes up a very similar amount of floor space (instead, they are made to become taller, just as grand pianos are made to become longer).
The ‘spinet‘ style vertical piano is a very short vertical piano which is less than 38“ tall.
A ‘console‘ style vertical piano is between 38“ and 45“ tall. A ‘studio‘ style vertical piano is between 45” and 54” tall.
An upright style vertical piano is taller than 54“. Neither spinet nor upright pianos are made anymore.
Vertical pianos come in a number of different cabinet styles, including continental, institutional and furniture cabinets, with a large number of wood veneers.
Just as with grand pianos, all vertical pianos should be tuned twice a year.
