AEBEG#B | AEBEA♭B Open E/A - Guitar tuning, chords & scales
Step into a world of rich, resonant sound with the Deep Open A Major Seven tuning. This unique setup transforms your guitar into a deep-voiced instrument, ideal for blues, jazz, ambient soundscapes, or any genre that benefits from a profound, complex harmonic foundation. As a significantly lowered version of more common open tunings like Open G or C, it delivers a massive sonic presence and a distinctive, dark character.
Technical Analysis:
The open strings of this tuning ring out with the notes A1-E2-B2-E3-G#4-B3 (low to high). This sophisticated voicing forms an A Major Seven (add9) chord. It features the root (A), perfect fifth (E), major seventh (G#), and major ninth (B), providing an immediate rich and complex harmonic palette. The extremely low A string (A1) plunges far below standard tuning, serving as a powerful foundational bass note that gives your sound immense depth and resonance. This profound low-end makes it perfect for driving basslines or creating droning soundscapes.
Given the substantial drop in pitch for all strings, particularly the low A (7 semitones down from standard E), players will find that simple barre chords across the open strings will yield these rich A Major Seven (add9) voicings, which can then be easily transposed up the neck for other keys. The unique intervallic structure allows for expressive slide guitar playing, with the open chord serving as a harmonious drone. The original description notes that the low A provides a base for the IV chord, suggesting its utility in keys like E Major where A is the subdominant, offering a robust foundation for blues and rock progressions.
Open String Notes:
- String 6 (lowest): A1
- String 5: E2
- String 4: B2
- String 3: E3
- String 2: G#4
- String 1 (highest): B3
How to Tune to Deep Open A Major Seven:
All strings in this tuning are significantly lowered from standard EADGBe. Due to the extreme drop in pitch (multiple strings dropping by 5 or more semitones, with the lowest dropping by a full 7 semitones), it is highly recommended to use a heavier gauge string set to maintain proper string tension, intonation, and playability. Using standard gauge strings may result in very loose, floppy strings, especially for movements exceeding 4 semitones up or down.
- String 6 (Low E): Tune down 7 semitones from E2 to A1.
- String 5 (A): Tune down 5 semitones from A2 to E2.
- String 4 (D): Tune down 3 semitones from D3 to B2.
- String 3 (G): Tune down 3 semitones from G3 to E3.
- String 2 (B): Tune down 3 semitones from B3 to G#3. (Note: The provided target tuning note for this string is G#4. Please ensure this matches your intended tuning, as tuning down 3 semitones from B3 results in G#3.)
- String 1 (High E): Tune down 5 semitones from E4 to B3.
