问题：请帮忙翻译，谢谢Allsourceoffrictioncause 
All source of frictn cause tuning problems.For example,if the slot in an instrument's nut is too lose,the string will be pulled flat as it is played.A tight nut(or capo)will cause the string's pitch to change in step rather evenly. 
回答：一切摩擦源均会造成定弦问题。例如,若吉他指板上的活动木片处的缝槽过于宽松, 弦在演奏时就会被牵拉得松软、造成降音，而（吉他指板上的）活动木片紧绷而不松动会使弦的音高变得非常均匀合拍。
