The symbols for the introduction to the knowledge of notation are as follows:
1. The re-rising symbol (×) indicates that the basic tone level is raised by two semitones (a whole tone).
2. The heavy drop mark (bb) indicates that the basic sound level is lowered by two semitones (one whole tone).
3. A sharp sign (#) indicates that the basic sound level is raised by a semitone.
4. The flat sign (b) indicates that the basic sound level is lowered by a semitone.
5. The reduction mark (ヰ) indicates that the sound that has been raised or lowered is reduced.
6, pp (very weak).
7, p (weak).
8, mp (weak).
9, mf (medium strong).
1, f (strong).
11, ff (very strong).
12, sf (extremely strong).
in the notation, the symbols used to indicate the level of these sounds are marked with seven Arabic numerals, which are written as:
1 2 3 4 5 6 7 pronounced as: do re mi fa so la si. Notes are closely related to pitch, and there is no note without pitch.
Pitch:
Numeric symbols of notes, such as 1 2 3 4 5 6 7, indicate different pitches. You can understand notes and pitches intuitively on the piano keyboard. Broadly speaking, there are always seven notes in music.
the length of notes:
apart from the high and low notes in music, of course, they also indicate the length. Here is a basic musical term-beat. Beat is an important concept to express the length of notes.
