Reading Music makes playing easier and faster, especially when learning new songs or writing your own.

The lessons provided below include both Guitar Music Notation and Guitar TAB for comparison and your convenience.   Although we have split up the Lessons between Right & Left handed players the only difference is when Fretboard diagrams are displayed, since Written Music and Tab are universal or the same for both fretboards.
The guitar uses the Treble Clef with the notes shown below with TAB.

It should be noted that guitars have different length fretboards with anywhere between 20 to 24 frets.
The Treble Clef is also called the G clef because the inner curve of the clef symbol marks the horizontal line, marked in red in the diagram below, associated with the note G above middle C.   The Treble Clef is actually a stylised letter G.

The names of the four inner spaces of the Treble Clef read upwards to spell the word FACE.

The five lines read upwards to spell E G B D F which you can remember using the phrase 'Every Good Boy Deserves Fudge'.

Music notation describes the pitch, timing and duration of sounds & silence called musical Notes and Rests, which are represented by graphic symbols:
Notes -                   Rests -            

Notes and Rests are placed on a grid of horizontal lines separated by spaces. The grid is called a Staff or Stave. The plural form of either word is staves.
The Staff has 5 lines separated by 4 spaces as seen below.

Notes may sit on a line (where the line passes through the note-head), in the space between two lines (where the note-head lies between two adjacent lines), in the space above the top line or on the space below the bottom line.

Notes outside the range covered by the lines and spaces of the staff are placed on, above or below shorter lines, called Leger Lines, which can be placed above or below the staff.

The higher the pitch of the note, the higher vertically the note will be placed on the staff.   Notes are named using the letters from the Music Alphabet;

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