Verbal Analysis:

The "Flutterbat Tuning," as described for Dusk@Twilight (Teddy Belair)'s song "Flutterbat," presents a deeply resonant and somewhat dark soundscape, moving far beyond standard guitar tunings. This isn't a tuning for casual strumming of major chords; it's designed to evoke a specific, perhaps atmospheric or even unsettling mood. The very low D on the 6th string combined with an unusual A# (A sharp) on the 2nd string creates an intriguing harmonic tension. It feels like a tuning crafted for specific melodic or rhythmic ideas, possibly in a progressive or ambient context, where conventional chord structures are less important than texture and mood. The name "Flutterbat" itself suggests something ethereal, perhaps a bit spooky, and the tuning certainly delivers on that promise with its unique blend of low-end depth and unexpected harmonic turns.

Technical Analysis:

This tuning deviates significantly from standard EADGBe, offering a distinct sonic palette:

• The lowest string (6th) is dropped a whole step to D2, providing a deep, guttural bass foundation.
• The 5th string remains at A2, creating a strong perfect 5th interval with the low D, establishing a powerful low-end D drone.
• The 4th string is also tuned to A2, a substantial drop of a perfect fourth from its standard D. This unusual duplication of A notes on adjacent strings (5th and 4th) creates a thick, layered octave or unison effect, emphasizing the fifth of D.
• The 3rd string drops a minor third to E3 from its standard G3. This E functions as the 2nd (or 9th) relative to the D root.
• The most striking feature is the 2nd string, tuned down a semitone to A#4 (B♭4) from its standard B4. In relation to the low D, this A# acts as an augmented fifth, creating a strong dissonance or a leading tone effect depending on context. This is a primary source of the tuning's unique, slightly unsettling character.
• The 1st string remains at standard E4.

The overall tuning is: D2 A2 A2 E3 A#4 E4.

Open Chords and Possibilities:

This tuning does not readily form conventional open major or minor chords due to the inclusion of the A# (B♭). Instead, it encourages a more textural and interval-based approach:

• D Power Chord/Drone: The lowest three strings (D-A-A) naturally form a strong D power chord or a resonant D drone, perfect for heavy riffs or sustained low notes.
• Dsus2 Implications: Playing the 6th, 5th, 4th, and 3rd strings (D-A-A-E) creates a rich Dsus2/9 flavor, offering a full, open sound with a resonant low end.
• Dissonance and Tension: The A# on the 2nd string provides significant harmonic tension against the root D and the surrounding A and E notes. This can be intentionally exploited for atmospheric leads, dissonant textures, or to create a sense of unresolved tension that fits a mysterious or dark mood.
• Melodic Playing: The tuning is highly effective for melodic lines that weave around the static lower strings, using the A# as a bluesy or exotic color tone. Players are encouraged to experiment with open voicings by muting strings or using partial chords to discover unique harmonic clusters.

How to Tune:

To achieve the Flutterbat Tuning from standard EADGBe, follow these string movements:

• String 6 (Low E): Tune down 2 semitones to D2. (This is a standard drop-D adjustment, generally safe for most string gauges).
• String 5 (A): Keep as is; no change (0 semitones). It remains A2.
• String 4 (D): Tune down 5 semitones to A2. This is a significant drop of a perfect fourth. Tuning down 5 semitones may cause the string to feel very slack, potentially leading to intonation issues or fret buzz. For optimal performance, especially in live or recording situations, considering a heavier gauge string for this position is advised to maintain adequate tension.
• String 3 (G): Tune down 3 semitones to E3. (This is a common adjustment for various tunings and is generally safe).
• String 2 (B): Tune down 1 semitones to A#4. (A slight adjustment, generally safe).
• String 1 (High E): Keep as is; no change (0 semitones). It remains E4.

String 6 (Low E): Tuned to D2.

String 5 (A): Tuned to A2.

String 4 (D): Tuned to A2.

String 3 (G): Tuned to E3.

String 2 (B): Tuned to A4#.

String 1 (High E): Tuned to E4.
