Adding a small dot above the note means singing an octave higher, adding two dots means singing two octaves higher;

On the contrary, adding a circle below Dot means singing an octave lower, adding two dots means singing two octaves lower.

1. The so-called simplified music notation refers to a simple notation method. There are two types of alphabetical notation and number notation. Commonly referred to as scientific notation refers to numerical simplified musical notation. The digital musical notation is based on the movable solfa method, using 1, 2, 3, 4, 5, 6, and 7 to represent the 7 basic sound levels in the scale, which are pronounced as do, re, mi, fa, sol, la, si , rest is represented by O.

2. In the simplified musical notation system, the relative height of a sound is represented by seven Arabic numerals. The relationship between these tones is that except for 3 4 and 7 i which are semitones, the others are all whole tones. Mark: 1 2 3 4 5 6 7 i Singing method: do ri mi fa sol la si do Adding a small dot above the note means singing an octave higher, adding two dots means singing two octaves higher; vice versa , adding a dot below means singing an octave lower, adding two dots means singing two octaves lower. To accurately represent the absolute height of a note, key signature markings are also applied. Key signature marks are represented by 1=F, 1=G?, etc. In order to avoid adding too many dots above or below the notes, in chorus and ensemble scores, the method of moving up or down an octave is often used to record the low or high parts. For example: tenor, bass, pipa, and low Hu are notated in a higher octave; bangdi and banhu are notated in a lower octave, etc. The length of the note is represented by adding a dash behind or below the note. Dotted points are also used in the simplified musical notation system. But only up to the quarter note; longer notes, such as half notes and whole notes, continue to be represented by adding dashes.
