This book uses standard music notation and tablature. If you cannot read music notes, use the tab written below the music. Music readers will need to look at the tab to see which technique is 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 one of the six strings on the guitar.
This indicates the seventh fret of the 5th string (an E note).
This indicates the 3rd string open (a G note).
