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 of the guitar. Study the following diagram.
When a number is placed on one of the lines, it indicates the fret location of a note e.g.:
This indicates the open 3rd string (a G note).
This indicates the 3rd fret of the 5th string (a C note).
This indicates the 1st fret of the 1st string (an F note).
The tablature, as used in this book, does not indicate the time values of the notes, only their position on the fretboard. You can read the time values by following the count written beneath the tablature. e.g.:
In this example the 1st note is worth 1 count, the 2nd and 3rd notes are worth half a count each and the 4th note is worth 2 counts.
