music theory

Music theory is how to learn about the notation, knowing about the pattern, pattern and structure of a notation that is in the music, and learn about rhythm, rhythm, time signatures, key signatures, and chord progression including how to play properly, in accordance with the standards of music itself

key signatures

if we play music , we will find about key signature, direction about sharps (#) and flats (b) to be use is called key signature. and we must remember piece of music is based on the notes of the scale of C major does not mean the it is restricted to eight notes, but the eight notes of the basic scale can be used at any pitch, one or more octaves higher or lower. example we play on G major, so F major become F# . it is not necessary to write in the sharps or flats every time they are needed.

CIRCLE 5TH /4TH

C   = 0  
G   = #1 (F)
D   = #2 (F,C)
A   = #3 (F,C,G)
E   = #4  (F,C,G,D)
B   = #5  (F,C,G,D,A)
F# = #6  (F,C,G,D,A,E)


F   = b1 (B)
Bb = b2 (B,E)
Eb = b3 (B,E,A)
Ab = b4 (B,E,A,D)
Db = b5 (B,E,A,D,G)
Gb = b6 (B,E,A,D,G,C)
