Acoustic Grand Piano
Also known as horizontal pianos is the largest piano type, and frequently the most majestic. Grand Pianos are categorized by horizontal soundboards sometimes stretching up to 4 ft. The Soundboard is encased in a supportable opening platform that lifts on the left in a upwards direction. Dampers lie on top of the strings, adjacent to the hammers. The internal construction is braced with form-holders, usually made of wood, as well as the small equipped metal reinforcements. Essentially the casing is "bottomless" allowing one to see the soundboard support base, also of reinforced wood, which technically acts as the base. Keys consist of wood coated in ivory, or sometimes pure ivory, depending on the piano's manufacturers and classification. The grand piano has the standard 88 keys. Most of these pianos have sheet music piece platforms. A retractable cover slides over, or folds down on the keys.
