This tuning, whimsically named 'C#7sus2 inverted' and described by its creator as 'experimenting in the trees with a broken guitar,' presents a truly distinctive sonic palette for the Guitar. With every string tuned down, many quite significantly, this setup is poised to deliver a deep, resonant, and potentially raw or melancholic sound. The wide array of intervals across the strings suggests an open and expansive character, inviting exploration of ambient textures, expressive fingerstyle compositions, or powerful, low-end driven riffs. The 'inverted' aspect in its name hints at the unconventional arrangement of notes, creating unexpected harmonic possibilities and a unique playing experience.

Technical Analysis

The open string notes, from lowest to highest, are: C#3, G#3, B2, F#4, A#4, C#5. This creates a very broad and diverse harmonic landscape:

• String 6 (C#3) to String 5 (G#3): A Perfect 5th (+7 semitones), providing a strong foundational interval.
• String 5 (G#3) to String 4 (B2): An exceptionally wide and unusual interval. B2 is 9 semitones below G#3, effectively creating a descending Major 6th or an ascending Augmented 4th (B2 to G#3). This large drop in pitch between adjacent strings will encourage unique voicings and arpeggios.
• String 4 (B2) to String 3 (F#4): A Perfect 12th (+18 semitones, or an octave plus a perfect 5th). This is another very expansive interval, contributing to the open and resonant quality of the tuning.
• String 3 (F#4) to String 2 (A#4): A Major 3rd (+4 semitones), a more common and melodically rich interval.
• String 2 (A#4) to String 1 (C#5): A Minor 3rd (+3 semitones), another familiar and harmonically useful interval.

When played open, these strings (C#, G#, B, F#, A#, C#) form a complex sonority. Arranged from lowest C# (root), the notes are: C# (root), F# (perfect 4th), G# (perfect 5th), A# (major 6th), and B (minor 7th). This can be interpreted as a C#sus4(add6, b7) or C#sus4(add13, b7). It is important to note that this open chord structure does not strictly align with the common definition of a C#7sus2 (C#, D#, G#, B). The tuning's name likely reflects the creator's artistic vision, an intended characteristic sound, or a specific intervallic quality they were aiming for, rather than a direct chordal representation of the open strings. The substantial drop in pitch across multiple strings, particularly on the 6th, 4th, and 1st strings (each by 3 semitones), will result in significantly lower string tension and a darker, more resonant timbre. This tuning is ideal for exploring vast, open chord voicings and creating atmospheric or heavy sonic landscapes.

How to Tune

To set your guitar to the 'C#7sus2 inverted' tuning from standard EADGBe, follow these precise string adjustments:

• String 6 (Low E): Tune down 3 semitones from E to C#3. (Tuning down 3 semitones will result in significantly lower string tension, which may feel loose. For optimal playability and tone, players might consider a heavier gauge string if this tuning is used frequently.)
• String 5 (A): Tune down 1 semitones from A to G#3.
• String 4 (D): Tune down 3 semitones from D to B2. (Tuning down 3 semitones will result in significantly lower string tension, which may feel loose. For optimal playability and tone, players might consider a heavier gauge string if this tuning is used frequently.)
• String 3 (G): Tune down 1 semitones from G to F#4.
• String 2 (B): Tune down 1 semitones from B to A#4.
• String 1 (High E): Tune down 3 semitones from E to C#5. (Tuning down 3 semitones will result in significantly lower string tension, which may feel loose. For optimal playability and tone, players might consider a heavier gauge string if this tuning is used frequently.)

These precise adjustments will transform your guitar into the distinct 'C#7sus2 inverted' tuning, ready for unique musical exploration.
