Fundamentals of music theory (brief introduction)

staff

from Five parallel lines with equal distance Composed of , Used to record note or Stop sign The music score of , There are five lines from bottom to top , There are four rooms . We count from bottom to top , the first line , second-line , The third line , Fourth line , The fifth line . Still counting from bottom to top , It is divided into the first room , Second room , The third room , The fourth room .

Musical sound

Generally speaking , Used in music , A sound with a fixed pitch is called a musical sound

Start with the next line , To the third line . There are seven tones . The difference is

 Add a line below , Add one room below , the first line , The first one , second-line , Second room , The third line 

They have their own names . They correspond to the following

 Add a line below , Add one room below , the first line , The first one , second-line , Second room , The third line 
  C         D       E       F      G      A      B
  c         d       e       f      g      a      b

D, G, E, B, A, F, C

 Add a line below , Add one room below , the first line , The first one , second-line , Second room , The third line 
  C         D       E       F      G      A      B
  do        re      mi     fa     sol     la     si

Roll call practice

re, sol, mi, si, la, fa, do

Clef

Clef is a symbol used to determine the pitch position of a note on the staff

Grouping of sounds

The highest sound on the keyboard , It should be five groups of small characters do. To this end .

Homophony

Isophones are easy to understand, which means they sound the same pitch , It's different names . It could be a phoneme , It may also be a roll call .

Basic sound level

Seven levels with independent names . From the center C Start up ,do re mi fa sol la xi;

Change the sound level

If you increase or decrease the basic sound level , It's called changing the pitch . Press down do When , Press the first black key on the right , elevated . He is in the original do On the basis of , Raised by a halftone .

Homophony

It's rising do When , Yes do The first black key on the right , Falling re When , This black key is also used （re The first black key on the left of ） （ l C drop D） So this key , It becomes two different names , One is called Sheng C, One is called Jiang D

Changing the tone level is not necessarily produced on the black key , It can also be generated on the white key .

note

Simple notes

The symbol head is divided into hollow and Solid , The stem of the symbol is head down when writing , There are also head up .

Let's put the solid symbol head , Add Fu Gan , Such notes , We call it a quarter note . He usually takes one shot , But the speed of each shot is not absolute .

Two quarter notes added together , It becomes a diaeresis . It's a hollow symbol , Add Fu Gan , His time is twice as long as the quarter note just now .

Add two diaeresis together , It becomes a whole note . We only need a hollow symbol head . He said four beats

Two quavers make up a quarter note , So an eighth note is half the length of a quarter note . His writing is as follows , By solid symbol head , Fu Gan , And a tail .

When two quavers or more are written together , His tail appears in this form .

Whether written alone , Or write together , His time value is constant .

A sixteenth note , It's a quarter shot , So four sixteenth notes are a beat , So four sixteenth notes form a group , Both ends become horizontal , Thirty two notes become three horizontal tails . The bottom one connects both sides .

Attach notes

A punctuation note is a small punctuation after a simple note .

The whole note with a dot is composed of the original four beats , It turns into six beats , in other words , The latter dot is half the time value of the previous note .

Floating point diaeresis becomes three beats . Floating point quarter notes become a beat and a half . The extra octave becomes three quarters of a beat .

Add a few notes

Express , Beats of full note , Add the second beat of half full note and half half half half note , Add a half of a half note, that is, a beat of a quarter note . The total is 4 + 2 + 1 = 7 pat .

How to write notes

Let's take the third line of the staff as an example , Higher than the third line , That is, go up , The third room , Fourth line , The fourth room , The fifth line … These sounds , Are higher than the third line . Go down , Second room , second-line , The first one , the first line … These sounds , Are lower than the third line . So the third line shall prevail , Higher than the third line , Fu Gan wrote down . Lower than the third line , Fu Ganchong writes . And the sound of the third line , Is the most flexible , You can rush up , You can also rush down .
