Some students for various reason have a hard time understanding how to get started with the exercises in the Music Theory Workbook for Guitar Volume One.  Below is a demonstration of one way to get started. 
    First if we look at the Basic Intervals exercises on page 22.  We see that we have two tasks to do.  One figure out what note to put above the fixed pitch in each exercise and second to figure out where these notes would be on a guitar fretboard and place these on the guitar diagram.  Let's first look at the exercises.

Lets look at the second example.  We have the note D (space below the first line of the staff).  We are asked to put a major 7th above this note.  So first we need to figure out what note is a Major 7th above D.  To do that we go to page 12 to figure out what a major 7th is.

We can see the Major 7th listed near the top of the page above and it says that a major 7th is 11 half steps.  So now we know that we need to put a note above the D that is eleven half steps.  To figure this out we go to page 9 where the chromatic scale is shown:

We need to put a Major 7th above that note and we have found that a C# is a major 7th or 11 half steps above the D.

You can see from the example above where the C# should be placed.  If at this point you are unsure if you are correct you can look in back of the book on page 115 and see if you have the correct answer.

Now we need to find out where to place these notes on the guitar fretboard.  First below is the answer.

First we need to go to the back of the book to find out where we can find a D and C# on the guitar fretboard.

If we go to page 200 we can see that a D can be found at the 5th fret on the A string and the C# can be found on 2nd fret of the B string.  Therefore we would enter:

By putting a 5 next to the D note we indicate that the correct pitch is located on the 5 fret of the A string.

While this all may seem like a lot of work hundreds of students have worked their way through this book and have found that within a few pages of work they can skip some of the steps above because they begin to recognize that patterns of the intervals on the guitar fretboard.  But the important distinction is they know what the notes are and not just a pattern. 

There are other ways of working through the Music Theory Workbook.  Please see the Help files for Music Theory Workbook for Guitar Volume One in the member's area for more help files.
