What does 1=C mean in jianpu? 简谱里的 1=C 是什么意思？
It tells you which note is “do”. In 1=C, the numbers 1 2 3 4 5 6 7 are C D E F G A B (do re mi fa sol la ti). In 1=D, 1 is D; in 1=B♭, 1 is B♭, and so on. Choose the key on this fingerboard and every note is relabelled for you.
它表示 do（1）是哪个音。1=C 时，1 2 3 4 5 6 7 就是 C D E F G A B；1=D 时 1 是 D；1=B♭ 时 1 是 B♭。在指板上选好调，所有音都会自动换成对应的简谱数字。
What do the dots above and below jianpu numbers mean? 简谱数字上面和下面的点是什么意思？
A dot below a number means one octave lower; two dots stacked below mean two octaves lower. A dot above means one octave higher; two dots above mean two octaves higher. For 1=C, middle C (C4) is plain 1 — 3rd finger on the G string. The open C string is 1 with a dot below, and C5 on the A string is 1 with a dot above.
数字下面一个点表示低八度，下面两个点表示低两个八度；上面一个点表示高八度，上面两个点表示高两个八度。例如 1=C 时，中央 C（C4）就是不带点的 1，在 G 弦上用三指；C 空弦是低音 1（下面一个点），A 弦上的 C5 是高音 1（上面一个点）。
Which finger plays each jianpu note on the viola? 简谱的每个音在中提琴上用哪个手指？
Pick the key and the position (1st, 2nd or 3rd). Coloured finger numbers 0–4 appear on the C, G, D and A strings, and a small gold mark shows where two fingers touch (a half step). The pattern changes with the key — that is the most useful thing to learn.
选好调和把位（第一、第二或第三把位），中提琴的四根弦上会显示 0–4 的彩色指法，金色小标记表示两个手指靠在一起（半音）。不同的调指法不同，这正是最值得熟练掌握的地方。
How is the viola page different from the violin page? 中提琴版和小提琴版有什么不同？
The viola has C, G, D and A strings — a fifth lower than the violin — and its music is written in the alto clef, switching to treble clef for high notes. The jianpu numbers work the same way: plain 1 is the one nearest middle C.
中提琴的四根弦是 C、G、D、A，比小提琴低五度，乐谱用中音谱号，高音部分改用高音谱号。简谱的读法一样：最接近中央 C 的 1 是不带点的 1。
