Hi Chuck

There are only the 7 whole notes ABCDEFG and their accidentals repeated through the octaves available to any fretted single string. i.e. the typical sequence G# or Aâ™­ => A => A# or Bâ™­ => B etc, etc, accidentals notated by convention depending upon ascending or descending sequence.

[br]It'd benefit your understanding best as well as answer your question far better to go and define accurately in your own mind what a "note" by definition is. Wikipedia can help you here.

Then understand what chords are, and how they are constructed to make them major, minor, 7th, 5th, suspended etc. Far too complex or circumspect to re-explain here. But reading it through even just the once will give you the general gist.

The guitar chords you will encounter most frequently in Fundamentals are most commonly tryads or dyads. By definition, a note attainable from fretting any single string anywhere on the neck can't be either.
