This book uses both standard music notation and tablature. If you cannot read music notes, use the tab written below the music. Music readers will need to use the tab to see the techniques being used to play certain notes (e.g. hammer-on, slide etc).
Tablature is a method of indicating the position of notes on the fretboard. There are six "tab" lines each representing a string on the guitar.
A number placed on a line indicates the fret location of the note.
This indicates the seventh fret of the 5th string (an E note).
This indicates the 3rd string open (a G note).
