2. The Basics: Notes, Scales, and the Fretboard
Understanding Notes
The musical alphabet consists of 12 notes:
A – A# – B – C – C# – D – D# – E – F – F# – G – G#
On the guitar fretboard, these notes repeat every 12 frets.
Example:
The open low E string plays E.
The 12th fret plays E again, but one octave higher.
What is a Scale?
A scale is a series of notes played in a specific order.
Example: The C Major Scale
C – D – E – F – G – A – B – C
Memorizing scales helps you improvise solos and create melodies.
3. Understanding Chords and How They Work
A chord is a group of three or more notes played together.
Types of Chords
✅ Major Chords → Happy & Bright (C, G, D, A, E)
✅ Minor Chords → Sad & Mysterious (Am, Em, Dm)
✅ Power Chords → Used in Rock & Metal (Root + Fifth)
How to Find Chords Easily
Memorize the CAGED System, which helps you locate chords all over the fretboard.
C Shape
A Shape
G Shape
E Shape
D Shape
This system is essential for mastering barre chords and lead playing.

🎸 I – IV – V → (C – F – G) → Classic in Blues & Rock
🎸 ii – V – I → (Dm – G – C) → Common in Jazz
Understanding progressions helps you write your own songs and improvise effortlessly.

C Major Scale → Used in Pop & Folk.

Example:
A Minor Scale → Used in Blues & Rock Ballads.
Learning both scales allows you to express different emotions through music.

Dorian Mode → Bluesy & Jazzy (Used by Santana)
Phrygian Mode → Dark & Mysterious (Used in Metal)
Mixolydian Mode → Bright & Funky (Used by John Mayer)
Modes help guitarists break out of standard scales and create unique solos.
