Tone names: C, D, E, F, G, A, B are used to mark the basic note levels, which are called note names. They represent a certain pitch, and their positions on the staff and keyboard are fixed. Its foreign name is pitch names.

Roll call: the seven basic tone levels do, re, mi, fa, sol, la, si (or ti) in the natural major mode.

Group of tone names

The seven basic tone levels are repeated repeatedly to form the entire sequence of musical tones.

The sequence of notes starting from C to C, an octave higher, is called a group. A group of sounds usually starting from the C sound in the second space of the bass clef, marked with lowercase Latin letters c, d, e, f, g, a, b, is called a small character group, and each group upwards is called One group of small characters, two groups of small characters, etc.;

The groups going down are marked with capital Latin letters in turn, called the group of large characters, one group of large characters, the second group of large characters, etc. The small c in the group is located on the central plus line of the large staff, so it is called middle C; it is also located in the center on the keyboard.

In addition, there are also those with middle C as the small group; the musical instrument manufacturing industry uses the numerical sequence of piano keys as the standard; the American Standards Association, based on the initiative of the Acoustical Society, uses the three octaves below middle C The C sound is the beginning of the first group, labeled C1, and then proceeds to C7, which is now commonly used in the Western acoustic community. Extended information

Various musical notations are just expressed in different forms. A sound will have different notes in different music scores, and it can be sung into different "roll calls" by different people according to their habits, but the sound you want to sing can only be this one.

So notes and "roll call" are a crucial factor in musical notation, and they are also an important key to discussing the characteristics of a musical notation. According to the general concept, it is directly called - "roll call".

Fixed solfa:

Sing the note names C, D, E, F, G, A, B as do, re, mi, fa, sol, la respectively , si, is fixed and does not change the singing method according to changes in tonality and mode. This singing (notation) method is called "fixed solfa" (that is to say, the solfa of each note is fixed.)

The treble of each note is fixed, its position on the keyboard and violin is also fixed, and its position on the staff is also fixed. Then fix their roll calls so that their corresponding relationships are all the same. It is fixed, so when you see the note on the score, you will immediately think of its roll call and its position on the violin. Very convenient for learning piano and violin.
