Verbal Analysis:

The Bunn Tuning is an extraordinarily low and heavy baritone guitar setup, designed for a profoundly deep and resonant soundscape. With all strings tuned down a staggering nine semitones from their typical standard guitar pitches, it plunges the instrument into the sub-bass frequencies, creating a weighty, almost orchestral sonic foundation. This tuning is perfectly suited for genres demanding immense sonic impact, such as doom metal, sludge, djent, or for crafting ambient and atmospheric textures with an unparalleled sense of gravitas. The extreme down-tuning, indicated by the (-9) in its description, means that standard gauge strings would be excessively slack and unplayable, necessitating the use of heavy baritone or even bass guitar strings to maintain proper tension, playability, and intonation.

Technical Analysis:

This Baritone G C F A# D G tuning features the following open notes from low to high: G1, C2, F2, A#3, D3, G3. Let's examine the intervals between the open strings, which reveal its unique harmonic character:

• 6th String (G1) to 5th String (C2): Perfect Fourth (P4)
• 5th String (C2) to 4th String (F2): Perfect Fourth (P4)
• 4th String (F2) to 3rd String (A#3): Augmented Fourth / Tritone (A4) - This dissonant interval is a key characteristic of the tuning, offering significant tension and unique harmonic possibilities that can be leveraged for blues, jazz, or modern heavy music.
• 3rd String (A#3) to 2nd String (D3): Major Third (M3)
• 2nd String (D3) to 1st String (G3): Perfect Fourth (P4)

While not a conventional open chord tuning like Open G or Open D, the specific combination of perfect fourths, a prominent tritone, and a major third creates a rich and versatile harmonic palette. The lowest three strings (G-C-F) lend themselves well to forming power chords (G5, C5, F5) or implying suspended harmonies, providing a deep, guttural foundation. The higher D-G strings offer familiar perfect fourth voicings, allowing for accessible melodic and rhythmic patterns. The tritone between F2 and A#3 is a potent interval for crafting tension-filled riffs, dissonant arpeggios, or exploring unique modal voicings. Due to the extremely low range, simple two or three-finger chord shapes will resonate with incredible depth and sustained power, making this tuning ideal for creating massive, slow, and grinding riffs.

Open String Notes:

• 6th String (Low): G1
• 5th String: C2
• 4th String: F2
• 3rd String: A#3
• 2nd String: D3
• 1st String (High): G3

How to Tune:

Important Note: This tuning requires a drastic down-tuning of all strings by 9 semitones from standard pitch. For optimal playability, stable intonation, and to prevent string breakage or excessive slackness, it is absolutely essential to use a set of heavier gauge strings specifically designed for baritone or extended-range guitars. Attempting to tune standard guitar strings this low will result in extreme looseness, poor intonation, and an unsatisfactory playing experience.

• 6th String (Low): Tune down 9 semitones to G1.
• 5th String: Tune down 9 semitones to C2.
• 4th String: Tune down 9 semitones to F2.
• 3rd String: Tune down 9 semitones to A#3.
• 2nd String: Tune down 9 semitones to D3.
• 1st String (High): Tune down 9 semitones to G3.
