Scales can be confusing for guitar students because:

1. You can play the same note in more than one place on the guitar.

2. Some patterns aren't always possible near the nut when your pattern runs up against the open strings.

3. Some patterns change when they cross from the G string to the B string, because all the strings are tuned 5 frets apart except for those 2 strings which are 4 fret apart.

I explain the basic possible major scale shapes in this tutorial.

So, using that as a guide you can play a G major scale like this:

|---------------------------------------------------|

|---------------------------------------------------|

|---------------------0----------------------------|

|-------------0-2-4-------------------------------|

|-----0-2-3---------------------------------------|

|--3-----------------------------------------------|

Or this:

|-----------------------------------------------------|

|-----------------------------------------------------|

|-----------------------------------------------------|

|---------------2-4-5-------------------------------|

|-------2-3-5---------------------------------------|

|--3-5-----------------------------------------------|

And an F major scale like this:

|------------------0-1-------------------------------|

|-------------1-3------------------------------------|

|-----0-2-3-----------------------------------------|

|--3-------------------------------------------------|

|-----------------------------------------------------|

|-----------------------------------------------------|

Or this:

|-----------------------------------------------------|

|---------------3-5-6-------------------------------|

|-------2-3-5---------------------------------------|

|--3-5-----------------------------------------------|

|-----------------------------------------------------|

|-----------------------------------------------------|

Hope that helps!
