Scale Reference
E Major | Triads
The E major scale with all 7 diatonic triads mapped across the fretboard. Each triad is color-coded by scale degree, showing you how the harmony sits within the scale across every position.
Diatonic triads in E major
E major has 7 diatonic triads: E (I), F#m (ii), G#m (iii), A (IV), B (V), C#m (vi), D#dim (vii°). The I, IV, and V chords | E, A, and B | are the most commonly used and form the foundation of countless rock and country songs.
Mapping these triads across the fretboard shows you how they overlap with your scale patterns, making it much easier to connect rhythm and lead playing in the same key.
Why this matters
When you can see the triads inside the scale, soloing over chord changes becomes intuitive. You know which notes to target over each chord | the difference between playing in the key and playing over the chords.
