Verbal Analysis:

The "Sandre Tuning" is a distinctive and highly customized guitar tuning, specifically designed for original compositions, as noted by the creator. This tuning significantly departs from standard EADGBe, creating a soundscape that is both rich and somewhat melancholic. The arrangement of notes, particularly the unison A strings at the top and the D-G-D foundation, suggests a focus on resonance, drones, and unique chord voicings. It provides a deeper, more profound feel, moving many strings down, which often results in a looser string tension and a characteristic 'floppy' sound, especially on the top string. The open tuning feels like a variation of a D minor tonality but with an interesting added G, giving it a suspended or modal quality.

Technical Analysis:

The open string notes for Sandre Tuning are: D2-G2-D3-F3-A3-A3. This tuning can be broken down as follows:

• The lowest string (6th) is tuned to D2, providing a strong, deep root.
• The 5th string is G2, creating a perfect 4th interval with the 6th string (D-G).
• The 4th string is D3, an octave above the 6th string, reinforcing the D root and creating a perfect 5th with the 5th string (G-D).
• The 3rd string is F3, establishing a minor 3rd interval with the 4th string (D-F). This is crucial in defining the overall minor tonality of the open chord.
• The 2nd string is A3, forming a major 3rd interval with the 3rd string (F-A), completing a D minor triad (D-F-A) across strings 6, 4, 3, 2.
• The 1st string is also A3, creating a unison with the 2nd string. This unison allows for interesting drone effects, string bends, or a thicker, chorus-like sound on the highest notes.

When strummed open, the tuning forms the notes D, G, F, A. This can be interpreted as a D minor (add4) chord (D-F-A with an added G) or a Gsus4 chord over a D bass (G-D-F-A). The prominent D and A notes provide a stable harmonic foundation, while the G and F add a unique, slightly suspended and minor flavor. The tuning makes it particularly easy to access D minor voicings and related suspended chords. Barring across any fret will create variations of this Dm(add4) or Gsus4/D structure, making it highly intuitive for creating new melodic and harmonic ideas within this specific tonal landscape. The presence of two D's (low and mid) and two A's (high) offers great opportunities for drones and ringing open strings against fretted notes.

How to Tune:

To achieve the Sandre Tuning from standard EADGBe, follow these precise string adjustments:

• String 6 (Low E): Tune down 2 semitones from E2 to D2. This movement is moderate and should not require a change in string gauge.
• String 5 (A): Tune down 2 semitones from A2 to G2. This movement is moderate and should not require a change in string gauge.
• String 4 (D): Keep as is; no change (0 semitones). It remains D3.
• String 3 (G): Tune down 2 semitones from G3 to F3. This movement is moderate and should not require a change in string gauge.
• String 2 (B): Tune down 2 semitones from B3 to A3. This movement is moderate and should not require a change in string gauge.
• String 1 (High E): Tune down 7 semitones from E4 to A3. This is a significant drop. Tuning down 7 semitones (a perfect fifth) is a considerable change in tension. For optimal playability, tone, and to prevent string floppiness, especially if aggressive strumming or bending is desired, consider using a heavier gauge string for the first string.
