The "Fluttershy Tuning" for Guitar, as described by its creator, is crafted for specific songs involving Fluttershy. This unique tuning presents an interesting harmonic landscape, blending lower drones with a highly trebled string, designed to evoke a particular mood or character.

Technical Analysis

Comparing this to standard E-A-D-G-B-E tuning:

• The low E string (6th) is tuned down by 2 semitones to D2, contributing to a deeper, more resonant bass foundation.
• The A string (5th) remains at its standard A2 pitch.
• The D string (4th) is specified in the full tuning notes as F4#. This is a significant adjustment; from a standard D3, F4# is a jump of 15 semitones (D3 to D4 is 12, D4 to F4# is 3). It is crucial to note that the tuning instructions for this string specify tuning up 4 semitones from its standard pitch (D3), which would typically result in F#3. The listed target note F4# is an octave higher than F#3. Such a large upward tension increase (15 semitones) on a standard string gauge is highly discouraged and could lead to string breakage or neck damage. A much lighter gauge string would be essential if F4# is the true target, or the user should verify if F#3 is the intended note based on the movement instruction.
• The G string (3rd) remains at its standard G3 pitch.
• The B string (2nd) is tuned down by 2 semitones to A3.
• The high E string (1st) is tuned down by 2 semitones to D4.

The open strings D2-A2-F4#-G3-A3-D4 present a complex harmonic structure. The presence of D, A, and F# (regardless of octave for F4#) strongly implies a D Major tonality, forming a D Major triad (D-F#-A) across the low D, the altered 4th string, and the A strings. The G3 string adds a suspended quality or hints at a G major chord, potentially creating a Dsus4add2 sound, or even a Gmaj9/D voicing. The repeated D and A notes provide strong drone capabilities, allowing for rich overtones. The extremely high F4# (if accurately maintained) would introduce a very bright, almost bell-like quality, drastically altering the guitar's typical voice in that register. This tuning lends itself well to open string arpeggios and melodic phrases that emphasize the ringing sustain of the open notes.

How to Tune

To achieve the "Fluttershy Tuning" from standard E-A-D-G-B-E tuning, follow these adjustments, noting the standard pitch for each string:

• 6th String (Standard E2): Tune down 2 semitones to D2.
• 5th String (Standard A2): Keep as is; no change (0 semitones) at A2.
• 4th String (Standard D3): Tune up 4 semitones to F#3. Please note: tuning up 4 semitones places this string at the upper limit for standard string gauges, and may require a lighter gauge string. If the ultimate target pitch is F4# as indicated in the full tuning notes, this would be an extreme upward adjustment of 15 semitones from D3, which is highly inadvisable with a standard string and would necessitate a much lighter gauge string to prevent breakage and potential instrument damage. Exercise extreme caution and verify your desired pitch.
• 3rd String (Standard G3): Keep as is; no change (0 semitones) at G3.
• 2nd String (Standard B3): Tune down 2 semitones to A3.
• 1st String (Standard E4): Tune down 2 semitones to D4.

When tuning up or down more than 4 semitones, it is generally recommended to use a different string gauge to ensure safety and optimal tension.

The "Fluttershy Tuning" sets your guitar strings as follows (from low E to high E):

• String 6 (low E string): D2
• String 5 (A string): A2
• String 4 (D string): F4#
• String 3 (G string): G3
• String 2 (B string): A3
• String 1 (high E string): D4
