Working Class Guitar · Lesson 2

Notes on the A String

In Lesson 1, we learned the landmark notes on the Low E string: G A B C D E. Now we are going to do the same thing on the A string. Same idea. Same frets. New root notes.

The A String Landmarks

These are the main A string notes we are learning first:

A String Fret Note
3C
5D
7E
8F
10G
12A

Why These Notes Matter

These notes are not just trivia. Every note on the A string can become the root of a chord.

  • Power chords
  • A-shape barre chords
  • Major chords
  • Minor chords
  • Scale positions
  • Lead guitar patterns
The Shortcut

Don’t just memorize a chord shape. Learn where the root note lives. Once you know the root, you can attach the chord shape to it.

A String Root Notes, Power Chords, and Barre Chords

This is the big connection. The note, the power chord, and the A-shape barre chord all come from the same root.

A String Fret Root Note Power Chord A-Shape Major
3CC5C Major
5DD5D Major
7EE5E Major
8FF5F Major
10GG5G Major
12AA5A Major

Example: C on the A String

The 3rd fret on the A string is C.

That means the 3rd fret can give you:

  • C root note
  • C5 power chord
  • C Major A-shape barre chord
  • C minor A-shape barre chord

Example: G on the A String

The 10th fret on the A string is G.

That means the 10th fret can give you:

  • G root note
  • G5 power chord
  • G Major A-shape barre chord
  • G minor A-shape barre chord

Connecting Lesson 1 and Lesson 2

Now you have landmark notes on the two most important strings for rhythm guitar: the Low E string and the A string.

String Landmark Notes Chord Shape Family
Low E String G A B C D E E-shape chords and power chords
A String C D E F G A A-shape chords and power chords

Quick Reference: Low E String

Here is the Lesson 1 chart again, so you can compare both strings side by side.

Low E String Fret Root Note Power Chord E-Shape Major
3GG5G Major
5AA5A Major
7BB5B Major
8CC5C Major
10DD5D Major
12EE5E Major

Practice Ideas

  • Play the A string notes forward: C D E F G A.
  • Play them backward: A G F E D C.
  • Say the note name out loud as you play it.
  • Play the root note, then build the power chord from that note.
  • Find the same chord on the Low E string and the A string when possible.
Working Class Guitar Rule

Find the root first. Then attach the shape. That one idea unlocks power chords, barre chords, scales, riffs, and songs.

Bonus: Practice Riffs and Song Connections

The best way to learn fretboard landmarks is to use them in real music. Lesson 1 and Lesson 2 gave us root notes on the Low E and A strings. Now it's time to put those notes to work.

Visit the Working Class Guitar Tablature Library and look for practice riffs, song intros, and examples that use the root notes we've learned so far.

Open the Tablature Library →

A great place to start is the Pennywise – Bro Hymn practice riff. As you learn the intro, pay attention to where the root notes fall on the Low E and A strings. Try identifying the roots before looking at the tab.

The goal isn't just to learn a song. The goal is to connect the notes, power chords, and fretboard landmarks to real music.
