The "Origami Angel Skeleton Key Tuning" is a distinctive and powerful tuning designed for sonic exploration, particularly suitable for the unique soundscapes associated with its namesake, Origami Angel. This tuning is characterized by its deep, resonant low end and intriguing harmonic relationships across the strings.

Technical Analysis:

• The open strings are tuned to C#3 G#3 D#3 G#4 C4 D#5, from lowest to highest.
• The tuning features a strong foundation with the lowest strings forming a C#5 power chord (C#3, G#3) with an added D#3, creating a C#sus2 (C#3, D#3, G#3).
• Noticeable is the repetition of G# (strings 5 and 3) and D# (strings 4 and 1), which contributes to a rich, layered sound.
• The intervals between adjacent strings are:
  • String 6 (C#3) to String 5 (G#3): Perfect 5th
  • String 5 (G#3) to String 4 (D#3): Perfect 5th
  • String 4 (D#3) to String 3 (G#4): Perfect 4th (transposed octave)
  • String 3 (G#4) to String 2 (C4): Diminished 5th (Tritone) – This interval introduces significant tension and can be used for dissonant voicings or interesting resolutions.
  • String 2 (C4) to String 1 (D#5): Minor 3rd (transposed octave)
• The overall tonality leans towards C# minor or a suspended C# sound, with the D# acting as a prominent second.

Playing Potential:

This tuning provides a powerful sonic palette. The low C# and G# notes are ideal for heavy, resonant riffs and power chords. Open chords like a C#5 (C#-G#) are easily voiced on the lower strings, and adding the D# on the 4th string gives a rich C#sus2. The double G# and D# notes allow for drone-like qualities and full, ringing chord voicings. The tritone between G#4 and C4 on the middle strings offers opportunities for unique melodic ideas and dissonant harmony, characteristic of modern rock and math rock genres. Despite some lower tunings, the high D#5 keeps melodic possibilities bright and clear.

How to Tune:

To achieve the "Origami Angel Skeleton Key Tuning," carefully adjust each string according to the following instructions. It's recommended to use a reliable digital tuner.

• 6th String (Low E): Tune down 3 semitones to C3#.
• 5th String (A): Tune down 1 semitone to G3#.
• 4th String (D): Tune down 11 semitones to D3#. Please exercise extreme caution when tuning this string. Tuning down 11 semitones is a significant change, and using a different gauge string might be advisable to maintain proper tension and avoid breakage.
• 3rd String (G): Tune up 1 semitone to G4#.
• 2nd String (B): Tune up 1 semitone to C4.
• 1st String (High E): Tune down 1 semitone to D5#.

Always check your guitar's intonation after significantly changing tunings to ensure accurate pitch across the fretboard.

Here are the notes for each string in this tuning, from the lowest (6th) to the highest (1st):

• 6th String: C3#
• 5th String: G3#
• 4th String: D3#
• 3rd String: G4#
• 2nd String: C4
