Verbal Analysis:

This is a distinctly bright and unconventional guitar tuning that elevates the overall pitch of the instrument. Unlike many alternative tunings that aim for lower, heavier sounds, "Alt A#1" lifts almost all strings significantly. The open string voicing creates a rich, complex sonority, notably an A# minor 7th suspended 4th chord, suggesting an intriguing harmonic palette for exploration. This tuning would be well-suited for genres like jazz fusion, progressive rock, or even ambient music, where unique voicings and shimmering textures are desired. The higher tension across most strings might require a lighter touch or specific string gauges.

Technical Analysis:

This is an altered tuning for a 6-string guitar. The open notes are A#2, G#3, C#4, G#4, A#4, D#5.

Open String Intervals (from low to high):

• String 6 (A#2) to String 5 (G#3): Minor 7th (10 semitones)
• String 5 (G#3) to String 4 (C#4): Perfect 4th (5 semitones)
• String 4 (C#4) to String 3 (G#4): Perfect 4th (5 semitones)
• String 3 (G#4) to String 2 (A#4): Major 2nd (2 semitones)
• String 2 (A#4) to String 1 (D#5): Perfect 4th (5 semitones)

The collection of open string notes (A#, G#, C#, D#) forms an A# minor 7th suspended 4th chord (Root-b3-P4-b7), offering a complex open-string harmony. The prevalence of Perfect 4ths between most adjacent strings can facilitate predictable melodic and chordal movements, while the unique Minor 7th and Major 2nd intervals will challenge and inspire new fretboard approaches. Players should be aware that all strings are tuned up, with significant tension increases.

How to Tune:

• String 6 (A#2): Tune up 4 semitones.
• String 5 (G#3): Tune up 4 semitones.
• String 4 (C#4): Tune up 4 semitones.
• String 3 (G#4): Tune up 6 semitones. (Note: Tuning up 6 semitones is a significant change; consider using a lighter gauge string to avoid breakage or excessive tension.)
• String 2 (A#4): Tune up 3 semitones.
• String 1 (D#5): Tune up 4 semitones.
