About the G Minor add 9th Tuning

The G Minor add 9th tuning transforms your guitar into an instrument capable of producing a rich, melancholic, and sophisticated sound. With open strings tuned to D2-A2-D3-G3-A#4-D4, this tuning creates an open G minor add 9th chord (G-Bb-D-A), offering a full, resonant texture without fretting.

Verbal Analysis

This tuning immediately conjures a deep, soulful, and slightly somber atmosphere. The added 9th (A) against the G minor triad (G-Bb-D) provides a lush harmonic complexity, making it excellent for genres that benefit from expressive harmony such as folk, blues, ambient, or indie rock. It's particularly well-suited for fingerstyle playing, slide guitar, or creating droning soundscapes where the open strings can ring out freely. The inherent minor tonality with the added richness gives it a sophisticated edge, moving beyond a simple minor chord into something more intriguing and emotionally resonant.

Technical Analysis

• Open String Notes: The tuning presents the notes D2, A2, D3, G3, A#4 (Bb4), D4 from low to high.
• Chord Structure: These notes collectively form a G minor add 9th chord (Root: G, Minor 3rd: A#/Bb, Perfect 5th: D, Major 9th: A). The repeated D notes (on strings 6, 4, and 1) provide a strong, resonant foundation, while the low A on string 5 firmly establishes the 9th.
• Intervals:
  • String 6 (D2) to String 5 (A2): Perfect 5th (7 semitones)
  • String 5 (A2) to String 4 (D3): Perfect 4th (5 semitones)
  • String 4 (D3) to String 3 (G3): Perfect 4th (5 semitones)
  • String 3 (G3) to String 2 (A#4/Bb4): Minor 3rd (3 semitones)
  • String 2 (A#4/Bb4) to String 1 (D4): Perfect 4th (5 semitones)
• Chord Accessibility:
  • Open G minor add 9th: Played simply by strumming all open strings.
  • Barre Chords: Moving a single barre shape up and down the neck allows for playing minor add 9th chords in any key (e.g., a barre at the first fret yields G# minor add 9th, at the second fret A minor add 9th, etc.).
  • Other Chords: The presence of open D and A notes also facilitates easy access to various D minor, A minor, and suspended chords with minimal fingering. Simple finger placements can easily yield a straight G minor triad by muting string 5 and 2 (A and Bb).

Tuning Notes

• String 6 (Low E String): D2
• String 5 (A String): A2
• String 4 (D String): D3
• String 3 (G String): G3
• String 2 (B String): A#4 (Bb4)
• String 1 (High E String): D4

How to Tune from Standard E Standard (E-A-D-G-B-E)

To achieve the G Minor add 9th tuning, adjust each string as follows:

• String 6 (Low E): Tune down 2 semitones to D2. (Original E2)
• String 5 (A): Keep as is; no change (0 semitones). The note remains A2. (Original A2)
• String 4 (D): Keep as is; no change (0 semitones). The note remains D3. (Original D3)
• String 3 (G): Keep as is; no change (0 semitones). The note remains G3. (Original G3)
• String 2 (B): Tune down 1 semitone to A#4 (Bb4). (Original B3)
• String 1 (High E): Tune down 2 semitones to D4. (Original E4)

Note on String Tension: The required adjustments for this tuning are generally small (maximum of 2 semitones down on any string). This means it is typically safe for guitars with standard string gauges. Always tune carefully and be mindful of your guitar's tension. Significant changes (more than 4 semitones up or down) generally advise a different string gauge for optimal playability and safety, but this tuning falls within a safe range.
