在乐器发展史上有这种现象:某种乐器发明之后不久被淘汰了,可是为这种乐器所创作的器乐曲却取得很大成功并流传至今。十八世纪初著名的古典作曲大师巴赫给大提琴写下了五首无伴奏组曲。在这些组曲中作者尽可能地运用了当时大提琴的各种演奏技巧。但当时大提琴的演奏技巧尚未得到充分发展,又由于弓、弦制作的水平等原因,音色不够华丽。巴赫认为这是因为乐器本身的缺 This phenomenon has been observed in the history of musical instruments: the invention of a certain musical instrument was eliminated shortly after its invention, but the instrumental music created for this instrument has been very successful and has been passed down to this day.

Bach thinks this is because of the lack of musical instruments themselves
