介绍（中）	乔治和约翰·雅各布·阿斯特是出生于德国的长笛演奏家，他们于1778年左右移民到伦敦。约翰·雅各布（John Jacob）将搬到美国，在那里他既是一名毛皮商人，也是一名乐器经销商，销售他兄弟制造的进口乐器。随着方钢琴在十八世纪末越来越受欢迎，乔治·阿斯特开始制作英国风格的乐器，就像博物馆收藏的这个可爱的例子技术说明：桃花心木和桃花心木单板表壳，带有浅色和深色阶梯式条纹，在台座上，4个锥形支腿之间有搁板，支腿顶部有镀金黄铜螺栓盖；指南针FF-f3（61个键），象牙色的自然色，正面模制，黑色方块上的乌木碎片；英国单动式，无擒纵机构，木制头顶减震器臂从脊柱中的铰链板延伸，由细木杆提升；未穿孔的长方形调音针对角穿过音板，两根弦贯穿整个音板，24根弦缠绕；键盘左侧有2个手柄，上（后）提升阻尼器，下（前）提升垫木条，紧靠螺母前的琴弦；2个踏板，用于膨胀效果的盖的右侧升高部分，左侧操作前手柄；饰有鲜花的铭牌，两侧刻有铭文；可折叠乐谱架，附在铭牌背面；桥后用红色毛毡编织的细绳，桥深深地被根切（约6厘米）；盖子只粘在左侧；绿色丝绸的防尘罩。
介绍（英）	George and John Jacob Astor were flute makers born in Germany who immigrated to London around 1778. John Jacob would move to the United States where he was a fur trader as well as a musical instrument dealer who sold instruments made by his brother and imported. As the popularity of square pianos grew in the late eighteenth century, George Astor began building instruments in the English style, like this lovely example in the Museum's collection.
