1. In the notation, there are seven basic symbols used to express the pitch and its relationship, namely, 1, 2, 3, 4, 5, 6 and 7, which respectively represent do, re, mi, fa, sol, la and si.

2. It is impossible to express many high and low tones with only seven notes. In the notation, adding a ""above the basic notes means that the sound rises by an octave, which is called treble; Adding two ":"means that the sound rises by two octaves, which is called treble.

add a "..." below the basic note, which means that the note is lowered by an octave, which is called bass; Adding two ":"means that the sound is reduced by two octaves, which is called double bass. On the piano keyboard, * * * has five sound areas, from left to right, corresponding to high notes to low notes.

3. Decorative notes: The symbol indicating the pause (pause) of music in the score is called a rest. The rest of the notation is represented by O. Use ">" Or "□" or "sf" is marked on the top of the note, indicating that the note should be sung (played) forcefully

when ">" When it appears together with the "□" symbol, it means stronger. The termination line is made of two vertical lines, one of which is thin and the other is thick, with the thin one in front and the thick one behind, indicating that the music is over.

4. The musical notation of two tigers, in which the beat of the red box indicates the rhythm of your song, that is, each bar is four beats. The green box indicates sol's because of the long press. The yellow box indicates that a beat presses two notes at the same time, that is, chords.

5. The purple box is a stop symbol. The green box is an octave lower than the note.

Generally speaking, there are four basic elements in the composition of all music, and the most important ones are "the sound level" and "the sound length":

1. The sound level: any piece of music is composed of high and low tones. Looking straight from the piano, the lower the keyboard sound to the left, the higher the keyboard sound to the right.

2, the length of the sound: in addition to the sound level, there is another important factor is the length of the sound. The pitch and length of the notes determine that this piece of music is different from other pieces, so it becomes the most important basic element of music.

3. the intensity of sound: the intensity of music is easy to understand, also called intensity. A piece of music will always have some notes that are stronger than teaching and weaker in some places. The change of strength is one of the factors to express emotion in music works.

4. Sound quality: it can also be called timbre. That is, musical instruments or voices. Boys and girls with the same melody pitch sing different timbres; The timbre of violin and piano is different.

the above four items constitute the basic elements of any piece of music. It should be said that notation can basically mark these basic elements correctly.
