A collection of 90 pieces of music theory knowledge, which must be understood by those who learn guitar
1. The clef is a symbol used to determine the name and pitch of the sound level on the staff.
2. The staff table is to add the clef on the stave.
Commonly used single-line staves are:
(1) Treble clef (G clef)
(2) Bass clef (F clef)
(3) Alto clef (a kind of C clef) with the third line of the clef as a group of small characters c
(4) Tenor clef (a type of C clef) with the fourth line of the clef as a group of small characters c
Commonly used multi-line staves are:
(1) Big staff
(2) Joint staff
3. There are four types of sound: pitch, timbre, sound intensity, and sound value.
4. Sound is divided into music and noise.
5. The sum of the basic tones used in music is called the tone system.
6. Each tone in the musical tone system is called a tone level.
7. Arranging the tones in the musical tone system according to a certain pitch relationship and order is called a tone sequence.
8. The respective names of each tone level in the musical tone system are called tone names.
9. The do, re, mi, fa, sol, la, and si used for singing are called roll call.
10. The sound level named after the seven letters of CDEFGAB is called the basic sound level.
11. The sound obtained by raising or lowering the basic sound level is called the change sound level.
12. In order to distinguish the sounds with the same sound name but different pitches, the resulting groups are called sound groups.
13. The standard pronunciation is a group of small characters, a1=440
14. The absolute accurate height of each tone in the musical tone system and their relationship are called temperament. The common ones are the law of twelve equals, the law of five degrees of mutual generation, and the law of purity.
15. Enharmonic is the sound with the same pitch but different notation and meaning.
16. The semitone composed of two adjacent basic tone levels and the change level of these two basic tone levels is called natural semitone.
17. The whole tone composed of two adjacent basic sound levels and the changing sound levels of these two basic sound levels is called natural whole tone.
18. A semitone composed of a certain basic sound level and its changing sound level is called a changing semitone.
19. A whole tone composed of two basic sound levels separated by a basic sound level and its changing sound level is called a changing whole tone.
20. Two whole notes, whole notes, half notes, quarter notes, eighth notes, sixteenth notes, thirty-second notes, etc. These are called basic notes.
21. A small dot is added to the right of the basic note, and this note is a dotted note.
22. The small dot on the right side of the basic note is a dot, and its function is to extend the time of the previous basic note by half.
23. The marks used to indicate the increase or decrease of the sound level are called diacritic marks, and there are five kinds.
24. The regular alternation of strength and weakness is called rhythm.
25. One strong and one weak cycle repeats, which is the beat.
26. Rhythm type is the typical rhythm in music.
27. Each time segment in the beat is called a unit beat.
28. The unit beat of the beat is represented by a fixed note, which is the beat.
29. The sign indicating the time is called the time signature.
30. The part between one strong beat and the next strong beat is called a measure.
31. The music begins with the weak part of the beat, which is called the weak rise; the weak rise is the weak rise.
32. A single beat is a beat with only two or three beats per measure.
33. A beat composed of identical single beats is called a compound beat.
34. Different types of beats with the same unit beat time value combined in different orders are called mixed beats.
35. In music, various beats appear alternately, which is called changing beats.
36. Several different beats are performed alternately, called alternate beats.
37. The time value and strong or weak position of the unit beat are not obvious. It is also called Sanban, free beat.
