grand piano
A type of acoustic piano whose strings, frame and soundboard are laid out horizontally. Can be found in varying lengths between roughly five and ten feet, from the keyboard at one end to the tail at the other. Such an instrument carries a much larger footprint than an upright piano or spinet, but makes a much greater sonic and visual impact.
Occasionally, an electric or digital piano will be mounted in a grand piano-shaped case, such as found at post #527947.
