昨昏上課時學生Gih-tah斷線去,趁這个機會來簡單紹介民謠吉他ê線(弦)。
「民謠 / 古典」主要是照吉他線ê材質來分類:
民謠吉他是鐵線(鋼線);
古典吉他是Nylon線。
毋過其實Nylon線ê吉他除了古典演奏mā會凍彈唱Flamenco(華:佛朗明哥),鋼線吉他除了彈唱mā有人提來做純演奏...
轉--來咱主題:吉他ê鐵線(鋼線)
- 吉他六條線朗是鐵線
- 除了下跤尚幼兩條,頂懸四條(Wound String)有kńg(捲)無仝ê材質予in(怹 thay)會凍彈出卡低音而且線未sioⁿ(傷)粗無好chhih(拟)
- 一般定定看着黃銅(青銅;80/20Bronze)是80%銅佮20%siah(錫)ê合金(嘛有無仝比例ê)
- Phosphor Bronze / 紅銅是加入磷ê銅合金,看來卡紅,低音厚聲音卡「溫暖」。
- 除了尚時行彼兩種,mā有閣卡特殊ê弦,che(這)以後有閒沓沓仔來寫。

Tō(就)算講是仝款材質ê弦,卡粗卡幼又閣有無仝ê影響:
相片內底兩組尚幼彼條朗是0.010 inch(英吋)下跤這組最後來到0.050吋,頂懸組甲若0.047吋。
我佇遮用一个簡單ê表來整理吉他線佮聲音ê關係:
幼 ← → 粗
響 ← → 厚
割甲會疼 / 拟甲會疼
