Tuning Analysis: Gustavo A Mora P

This exceptionally unique tuning, named "Gustavo A Mora P" (identified internally as 'bbbfsbe'), transforms your standard Guitar into a resonant, heavy, and B-dominant instrument. It's crafted for a powerful, deep sound with surprising sonic contrasts. The foundation is a massive B octave spread across the lower three strings, creating an incredibly thick and sustained low end that is both guttural and resonant.

The open strings are tuned to B1-B2-B2-F#4-B3-E4, from the thickest to the thinnest. This configuration immediately strikes with its profound emphasis on the note B, making the instrument feel significantly deeper and more commanding than standard tuning. The first three strings, all B (B1, B2, B2), allow for incredibly deep, droning power chords and riffs. This sets a formidable stage for genres like metal, doom, progressive rock, or any style demanding a heavy sonic foundation.

Technically, the tuning offers a robust B5 power chord (B-F#) across strings 6, 5, 4, and 3 (B1-B2-B2-F#4), leveraging multiple octaves of B and the crucial perfect fifth, F#. The presence of E4 on the highest string, while the middle string is B3, creates an interesting tension or a potential Bsus4 (B-E-F#) if played with the F# string. The significant interval between the 4th string (B2) and the 3rd string (F#4) – a jump of an octave and a perfect fifth – means traditional chord shapes will need serious re-evaluation and adaptation. However, open power chords based on B will be exceptionally easy to achieve and will deliver immense sonic impact.

This tuning lends itself perfectly to powerful single-note riffs on the low B strings, creating a heavy, percussive, and driving sound. It also provides unique voicing opportunities on the higher strings due to the distinct intervals. While open chords will largely center around variations of B5 or Bsus4, the creative guitarist can explore dissonant or extended harmonies by leveraging the tuning's specific architecture, leading to truly original sonic landscapes.

How to Tune Your Guitar

To achieve the Gustavo A Mora P tuning from standard E-A-D-G-B-E, follow these specific string adjustments:

• String 6 (Low E to B1): Tune down 5 semitones. This is a significant drop, transforming your low E into a powerful B1.
• String 5 (A to B2): Tune up 2 semitones. Your A string will become B2, adding to the low B resonance.
• String 4 (D to B2): Tune down 3 semitones. This brings your D string down to B2, further reinforcing the deep B.
• String 3 (G to F#4): Tune down 1 semitone. Your G string will become F#4.
• String 2 (B to B3): Keep as is; no change (0 semitones). Your B string remains B3.
• String 1 (High E to E4): Keep as is; no change (0 semitones). Your high E string remains E4.

Important Note on String Tension: Tuning down 5 semitones on String 6 (Low E to B1) is a substantial change. For optimal playability, to maintain good intonation, and to prevent potential string breakage, it is highly recommended to use a heavier gauge string for this particular string when adopting this tuning. Generally, for any string requiring a movement of 4 or more semitones (up or down) from its standard pitch, considering a suitable heavier or lighter string gauge, respectively, will yield the best results.

Here are the notes for each string in the Gustavo A Mora P tuning, from the lowest (thickest) to the highest (thinnest):

• String 6: B1 (The lowest note, a very deep B, an octave and a perfect fourth below standard low E)
• String 5: B2 (An octave higher than String 6, a whole step above standard A)
• String 4: B2 (Unison with String 5, creating a thick, resonant low B, a minor third below standard D)
• String 3: F#4 (A very high F#, an octave and a major second above standard G)
• String 2: B3 (Retains its standard B string pitch)
• String 1: E4 (Retains its standard high E string pitch)
