Verbal Analysis: This unique "Gmaj7" tuning, born from an accidental downward tuning journey, offers a surprisingly rich and complex soundscape. It's a tuning that immediately evokes a sense of lushness, perhaps melancholic or dreamy, making it perfect for ambient textures, introspective fingerstyle pieces, or creating a unique backdrop for vocals. The wide intervals and spread voicings contribute to an expansive, open feel, encouraging exploration beyond standard chord shapes. It truly feels like a happy accident, as the original description implies.

Technical Analysis: The open strings are tuned to B1-G2-D3-F#4-B3-D4 (from lowest to highest). When analyzed, these notes (G, B, D, F#) perfectly form a G Major 7th chord. The presence of the root G, major third B, perfect fifth D, and major seventh F# creates a sophisticated harmonic foundation. Additionally, a clear B minor triad (B-D-F#) is prominent across several strings, offering a dual harmonic identity. The intervals between strings are varied, creating an interesting texture: a minor 6th from B1 to G2, a perfect 5th from G2 to D3, a major 3rd from D3 to F#4, a perfect 4th down from F#4 to B3, and a minor 3rd from B3 to D4. This non-linear intervalic structure makes for exciting voicings and chord possibilities.

Chordal Opportunities:

• Open Gmaj7: Strumming all open strings yields a beautiful, full G Major 7th chord, ready for immediate use in songwriting.
• B minor: The inherent B-D-F# structure means open B minor chords are easily accessible, allowing for melancholic or minor-key compositions.
• Shifting Textures: Barre chords become entirely new beasts. Sliding a finger up a single fret, for example, transforms the open Gmaj7 into an Abmaj7#11 (G-B-D-F# becomes G#-C-Eb-G#). Experimentation with single-finger barring or simple two-finger shapes can yield rich suspended chords, altered dominant 7ths, and unique major 7th inversions up the neck, making complex harmonies surprisingly within reach.

This tuning is a fantastic playground for those seeking to break away from standard chord voicings and discover fresh harmonic landscapes.

Tuning Notes:

6th String (Low E): Tuned to B1
5th String (A): Tuned to G2
4th String (D): Tuned to D3
3rd String (G): Tuned to F#4
2nd String (B): Tuned to B3
1st String (High E): Tuned to D4

How to Tune:

• 6th String (Low E): Tune down 5 semitones from E to B1. Caution: Tuning down 5 semitones is a significant change. A different gauge string is advised for sustained use to avoid potential intonation issues or string floppiness.
• 5th String (A): Tune down 2 semitones from A to G2.
• 4th String (D): Keep as is; no change (0 semitones) from D to D3.
• 3rd String (G): Tune down 1 semitone from G to F#4.
• 2nd String (B): Keep as is; no change (0 semitones) from B to B3.
• 1st String (High E): Tune down 2 semitones from E to D4.
