I graduated from the Conservatory of Music in 2003 and am now engaged in teaching electronic keyboard and vocal music. I know how to teach you, but you have to work hard. The simple composition you are talking about is song writing. Teach you how to read music in 10 minutes.

Staves: The hollow O is a whole note in 4 beats. Simplified notation: 1 - - -

Add a stem to be a half note in 2 beats 1 -

Then fill in the empty space to make it a quarter note 1 beat 1

Add another symbol to make it a half beat eighth note (1/2 beat) 1 (a short horizontal line below)

Add another half-beat that ends with a sixteenth note (1/4 beat) 1 (two dashes below)

The number of beats decreases every time the note is changed a little Half as small.

4/4 beat is a quarter note, and each measure has 4 beats.

3/4 beat is a quarter note, and each measure has 3 beats.

2/4 beat is a quarter note, and there are 2 beats in each measure.

A bar line of 4 beats (3 beats/2 beats) is a measure.

Stave notation: One # (#4) is G major. Simplified notation: if the tabs are all in C major, it is expressed as 1=G

Two # (#41) is D Major 1=D

Three #s (#415) are A major 1=A

Four #s (#4152) are E major 1=E

Five # (#41526) is the key of B major 1=B

One b (b7) is the simplified notation of F major: the charts are all in C major, expressed as 1=F

Two b (b73) is bB major 1=bB

Three b (b736) is bE major 1=bE

Four b ( b7362) is bA major 1=bA

Five b (b73625) is bD major 1=bD

Key: 1 2 3 4 5 6 7

Note name: C D E F G A B

Roll call: do re mi fa sol la si

C major is to sing C as do

D major is Sing D as do

. . . . . .

In bE major, bE is sung as do

#F major is as #F is sung as do

. . . . .

When singing, you need to use different height keys to sing the roll call of the same simplified score. To play the piano, you only need to know which note rises and which note falls on the staff.

5 1 (treble) 2 (treble) 6 6 3 7 7

Chords: C: 3 F: 6 G: 7 D: #4 Dm: 4 Am: 1 E :5 Em: #5

I don’t know how much you can understand. This is my teaching experience. I think you should Just understand these first and you don’t have to go looking for a needle in a haystack to read obscure music theory books. If you don’t understand, just ask. I'm willing to help you!
