大竖琴或更广为人知的音乐会竖琴或踏板竖琴是一种大型现代竖琴，主要用于古典音乐。大竖琴是凯尔特尼龙竖琴等古代竖琴的后代。竖琴被许多巴洛克和古典作曲家作为协奏曲的独奏乐器在早期的管弦乐中使用。它开始被赫克托·柏辽兹用于交响音乐。大竖琴的音调范围很广，为六个半八度（47 弦），通常从 C 1 开始，到 G 7 结束。最低的琴弦由铜或钢绕尼龙制成，中下弦肠线，和尼龙的中间到最高，或更多或全部肠线。
The Grand Harp or better known as Concert Harp or Pedal harp is a large modern harp, designed primarily for classical music. The Grand Harp is a descendant of ancient harps such as a Celtic Nylon Harp. The harp found its early orchestral use as a solo instrument in concerti by many baroque and classical composers. It began to be used in symphonic music by Hector Berlioz. The Grand Harp has a wide range of tones which is six and a half octaves (47 strings) starting typically from C 1 and ends up at G 7. The lowest strings are made of copper or steel-wound nylon, the middle-lower strings of gut, and the middle to highest of nylon, or more or all gut.
