图45弦首的制作——正面 弦首的正面有弦槽,是安装弦轴张紧琴弦的地方,为了美观而又兼顾到牢固,弦槽的两壁一般是制作成上薄下厚的,弦槽壁厚5mm～5.5mm上下,宽度一般在27mm～21mm之间,弦槽的形状和厚度是很具有表现力的。形状可以是直的,也可以略向外突出,可以较薄来表现轻巧,也可以较厚表现厚重,除美观外,弦槽的功能是很重要的。其深度应该是使弦轴上弦时不会摩擦槽底,但槽底又有一定的厚度以保证琴头的强度。
Figure 45 String head production - the front chord front has a chord, chord shaft is installed to tighten the string where, in order to look beautiful and take into account the firm, the chord of the two walls are generally made thin and thick , Chord wall thickness 5mm ~ 5.5mm up and down, the width is generally between 27mm ~ 21mm, chord shape and thickness is very expressive. The shape can be straight or slightly outward, thinner for lightness, thicker for thicker appearance. In addition to aesthetics, the function of the chordal groove is very important. The depth should be so chord shaft friction will not friction bottom, but there is a certain thickness of the bottom groove to ensure the strength of the piano head.
