This stunning piano comes to us from Steinway \u0026amp; Sons having been on lease at a UK University since new. The new GP215 costs well in excess of £45,000 so this represents an amazing opportunity to own a stunning grand piano for a fraction of the price!!\u003cbr\u003eThe GP215 III, at 7'1\" produces a staggering warmth \u0026amp; depth of tone from its solid Sitka spruce, tapered soundboard while the action is extremely responsive at both pianissimo \u0026amp; fortissimo levels. \u003cspan\u003eIn comparison to other pianos, the Boston has lower string tension. This reduced string tension, along with a tapered soundboard, creates longer sustain, and a more singing quality in the tone (as well as longer piano life). A wealth of other engineering enhancements, including optimal placement of ribs, braces, and bridges, also contribute to the Boston’s superior tone and greater stability.\u003c\/span\u003e\u003cbr\u003eThe Boston range is designed by Steinway \u0026amp; Sons \u0026amp; produced for them by renowned piano builders Kawai in Japan. This represents amazing value for money \u0026amp; one not to be missed!!\u003cbr\u003e\u003cstrong\u003ePete - Rimmers Music, The Piano People\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions\u003cbr\u003e\u003c\/strong\u003eLength: 215cm\u003cbr\u003eWidth: 155cm\u003cbr\u003eHeight: 102cm\u003cbr\u003e\u003cbr\u003eWeight: 404Kg\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eMore about the GP215 III\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp class=\"\"\u003e\u003cstrong\u003eRim\u003c\/strong\u003e\u003cbr\u003eHard Rock Maple inner rim -- this is the foundation of the Boston’s tone.
