Find All 'D' Notes on Guitar Fretboard
The Rocker's Key
D is the foundation of "Drop D" tuning and countless classic rock anthems. Knowing your D notes allows you to quickly identify power chords and riffs that utilize the open 4th string.
Visualization Strategy
Look for the "triangle" of D notes in open position: the open 4th string, the 3rd fret on the B string. Connecting these dots helps you see the "CAGED" D shape move up the neck.
