The Re`DXia tuning for a 7-string Guitar is a highly evocative and expansive setup, perfectly encapsulated by its description: 'Mimic (Open) Harp Melodic Ambient Emotion Lifting Drifting Void.' This tuning transforms your guitar into a resonant soundscape generator, ideal for creating atmospheric, ethereal, and emotionally rich music.

Verbal Analysis: The Sound of the Void

Re`DXia truly lives up to its name, crafting an almost harp-like, open sound. The arrangement of notes fosters a sense of spaciousness and sustain, where individual notes ring out and blend into harmonious textures. It's a tuning designed to evoke a feeling of emotional lift and gentle drifting, allowing melodies to float and chords to resonate with a shimmering quality. This makes it particularly suitable for ambient soundscapes, cinematic scores, modern classical compositions, or any genre where mood and atmosphere take precedence over traditional chord progressions. The 'void' aspect suggests an endless depth, perfect for sustained drones and evolving pads.

Technical Analysis: Open Harmonies and Reachable Chords

This 7-string tuning results in the following open notes, from the lowest (7th) to the highest (1st) string:

• 7th String: A1
• 6th String: C2
• 5th String: G2
• 4th String: C3
• 3rd String: G3
• 2nd String: B3
• 1st String: D4

The open strings themselves form a rich and complex harmony. Grouping the notes (A, C, G, C, G, B, D) reveals a C major foundation (C, G, C, G) augmented with significant extensions: the 7th string A, the B (major 7th) on the 2nd string, and the D (9th) on the 1st string. This forms an open Cmaj13 (no 3rd, no 5th) chord voicing (C, G, B, D, A) or more simply, a Cmaj9 (add6), creating an incredibly lush and resonant sound when strummed openly. This inherent richness means that even simple finger placements or barres will often yield sophisticated and pleasing harmonies.

The repetitive C-G-C-G pattern across the middle strings provides excellent drone potential and makes for easy exploration of melodic ideas over a static bass. The low A and high B and D add sparkle and depth, opening up possibilities for wide voicings and arpeggios that mimic the expansive range of a harp. Chords that involve barring across a single fret will translate into a series of harmonically rich major 9/13 type voicings, making it easy to achieve a full, polished sound with minimal effort. Shapes derived from open C or G chords will feel particularly natural, as these notes are strongly represented in the tuning.

How to Tune: Adjusting to the Re`DXia Void

To achieve the Re`DXia tuning, you will adjust your 7-string guitar from standard tuning (B-E-A-D-G-B-E). Please follow these instructions carefully:

• 7th String (Low B): Tune down 2 semitones to A1.
• 6th String (Low E): Tune down 4 semitones to C2. This is a significant drop; ensure your strings can handle the slack without buzzing.
• 5th String (A): Tune down 2 semitones to G2.
• 4th String (D): Tune down 2 semitones to C3.
• 3rd String (G): Keep as is; no change (0 semitones) to G3.
• 2nd String (B): Keep as is; no change (0 semitones) to B3.
• 1st String (High E): Tune down 2 semitones to D4.

Important Note on String Gauges: While most of the string movements are within a moderate range, the 6th string requires tuning down by 4 semitones. While this is often manageable with standard string gauges, you may experience some string slackness or buzzing. If you find yourself frequently using this tuning, or if you plan to tune further down from this point, considering a heavier gauge string for the 6th string could improve tension and tone. Conversely, tuning up more than 4 semitones from standard would generally necessitate a lighter gauge to avoid excessive tension and potential string breakage, though that is not the case for this specific tuning.

The open strings for the Re`DXia tuning are as follows (from lowest to highest pitch):

7th String (Low A): A1
6th String (Low C): C2
5th String (G): G2
4th String (C): C3
3rd String (G): G3
2nd String (B): B3
1st String (High D): D4
