The "My Kimono - Polvo" tuning, reportedly utilized by the band Polvo, crafts a uniquely resonant and expansive sonic landscape for the guitar. It's characterized by an extreme spread in string tension and pitch, ranging from a deeply resonant low B to a shimmering high B. The open strings B1-F#3-F#3-E3-B3-B4 immediately resolve into a rich and slightly suspended Bsus4 chord, providing a strong yet open harmonic foundation.

Verbal Analysis: This tuning conjures an ethereal, almost drone-like quality, amplified by the prominent B and F# notes across multiple octaves. The unison F#s on the 5th and 4th strings create a thick, harmonized mid-range, ideal for sustained notes and ringing arpeggios that fill the sound spectrum. The significant drops on the lower strings and a substantial raise on the highest string give the tuning a broad dynamic range, allowing for both deep, rumbling textures and bright, jangling melodies. It feels experimental and expressive, perfect for intricate fingerstyle or unconventional chord voicings that break away from standard guitar conventions. The open Bsus4 makes it sound both resolved and slightly yearning.

Technical Analysis: The open string notes are B1, F#3, F#3, E3, B3, B4. This configuration strongly emphasizes the notes of a Bsus4 chord (B, E, F#). The root note (B) is present on the 6th, 2nd, and 1st strings, spanning three octaves. The 5th (F#) is doubled on the 5th and 4th strings, while the 4th (E) sits on the 3rd string. The intervals between adjacent strings are particularly noteworthy: a wide perfect 5th (B1-F#3), a striking unison (F#3-F#3), a major 2nd (F#3-E3), a perfect 4th (E3-B3), and another perfect 4th (B3-B4). The unison F#s are a distinctive feature, enabling unique harmonic effects. Players will find open chord shapes based around Bsus4 easily accessible, and barre chords, especially across the F# strings, will yield interesting, complex voicings. This tuning offers a departure from traditional tonality, opening doors for creative exploration.

To achieve the "My Kimono - Polvo" tuning from standard E Standard, carefully adjust your strings as follows:

• 6th String (Low E to B1): Tune down 5 semitones. Caution: This is a significant drop (-5 semitones); a heavier gauge string may improve tension and clarity for the lowest note.
• 5th String (A to F#3): Tune down 3 semitones.
• 4th String (D to F#3): Tune down 8 semitones. Caution: This is a very significant drop; a heavier gauge string is strongly advised for optimal tension and playability if you plan to use this tuning frequently, to prevent floppiness and potential intonation issues.
• 3rd String (G to E3): Tune down 3 semitones.
• 2nd String (B to B3): Keep as is; no change (0 semitones).
• 1st String (High E to B4): Tune up 7 semitones. Caution: This is a very significant raise; a lighter gauge string is strongly advised to prevent breakage, and always tune up slowly and carefully to avoid excessive stress on the string and guitar neck.
