🎯 Step 1: Learn the 12 Notes of Music
- Music uses 12 notes that repeat in every octave
- These notes appear across your fretboard — not just in one spot
- Learn to locate notes on the low E and A strings first
✅ This forms the basis of chords, scales, and keys
🎸 Step 2: Understand Intervals
- Intervals are the distance between notes (like root to 3rd or 5th)
- They help you build chords and melodies
- Start by identifying intervals across a single string or between nearby strings
✅ Intervals turn the fretboard into a roadmap
🧱 Step 3: Master Chords with the CAGED System
- CAGED = 5 major chord shapes: C, A, G, E, D
- These shapes repeat and move across the neck
- Learn how to shift these to build chords in any key
✅ It’s the best visual system for self-taught players
🔄 Step 4: Practice Chord Progressions in Different Keys
- Learn I–IV–V and I–V–vi–IV — two of the most common patterns
- Practice them using open chords, then CAGED shapes
- Understand how chords function together in a key
✅ Now you’re using theory to create real music
🧠 Step 5: Explore Scales and Harmony
- Start with the major and minor pentatonic scales
- Learn how they align with the CAGED system
- Use them to improvise, write, and understand harmony
✅ Scales are more fun when tied to real musical goals
