The 'Valiant' tuning is an extremely low and unconventional 7-string guitar tuning, pushing the boundaries of what's typically expected from the instrument. Its name evokes a sense of boldness, fitting for a tuning that delves into such deep and challenging sonic territory. The overall sound profile would be incredibly profound and potentially dissonant, perfect for genres requiring maximal heaviness, unique textures, or experimental soundscapes like extreme metal, djent, noise, or progressive explorations.

While the tuning's provided description hints at a "drop F# with the low string tuned a 1/2 step lower," the actual intervallic structure defined by the notes is highly idiosyncratic and deviates significantly from standard 'drop' tunings. The massive intervallic jumps between strings suggest a tuning not intended for conventional chord shapes, but rather for single-note riffs, arpeggiated dissonances, or a highly specific, deconstructed approach to harmony. The deep F1 note anchors the tuning with a sub-bass rumble, while the higher strings provide unusual harmonic counterpoints.

Technical Analysis:

This 7-string tuning, named 'Valiant,' features the following notes from lowest (String 7) to highest (String 1):

• String 7: F1 (The lowest string, set to an incredibly profound F in the first octave, providing a fundamental sub-bass resonance.)
• String 6: F#3 (Tuned to F# in the third octave.)
• String 5: B2 (Tuned to B in the second octave.)
• String 4: E3 (Tuned to E in the third octave.)
• String 3: A3 (Tuned to A in the third octave.)
• String 2: C#5 (Tuned to C# in the fifth octave.)
• String 1: F#5 (The highest string, tuned to F# in the fifth octave.)

The tuning presents a series of extreme and irregular intervals between strings:

• A colossal leap occurs between String 7 (F1) and String 6 (F#3), spanning approximately two octaves and a semitone (25 semitones). This creates an extremely wide, thick, and potentially dissonant interval when played simultaneously.
• Another significant pitch drop is found between String 6 (F#3) and String 5 (B2), a descent of over an octave. This unexpected shift in pitch creates a very unique and challenging sonic texture.
• Strings 5, 4, and 3 (B2, E3, A3) maintain a consistent pattern of perfect fourths. This section provides a more familiar anchor, allowing for traditional perfect fourth-based power chords or melodic movements within this range.
• Between String 3 (A3) and String 2 (C#5), there's another substantial upward leap of an octave and a major third (16 semitones), dramatically increasing the pitch and creating another wide intervallic gap.
• The highest two strings, String 2 (C#5) and String 1 (F#5), once again form a perfect fourth interval, similar to the top two strings of a guitar in standard tuning, offering a familiar, albeit higher, melodic and harmonic space.

Due to these extreme and irregular intervals, conventional open chords are largely impractical or will yield highly dissonant and complex results. For instance, playing String 7 (F1) and String 6 (F#3) together would produce an incredibly thick, grinding minor second interval spread over a vast range. Power chords are most effectively formed on the segments with perfect fourths (B2-E3-A3 and C#5-F#5). The tuning might lend itself to specific melodic patterns that exploit the wide ranges, unison bends across large intervals, or drone-like textures with the lowest F1. This tuning demands a creative and experimental approach to composition and playing, pushing the instrument into truly new sonic territory and inviting exploration of its unique dissonant and resonant qualities.

Tuning Notes:

Please tune your 7-string guitar to the following notes, from the lowest (String 7) to the highest (String 1):

• String 7: F1 (The lowest string, tuned to F in the first octave, offering a profound, sub-bass register.)
• String 6: F#3 (Tuned to F# in the third octave.)
• String 5: B2 (Tuned to B in the second octave.)
• String 4: E3 (Tuned to E in the third octave.)
• String 3: A3 (Tuned to A in the third octave.)
• String 2: C#5 (Tuned to C# in the fifth octave.)
• String 1: F#5 (The highest string, tuned to F# in the fifth octave.)

How to Tune:

To achieve the 'Valiant' tuning, follow these specific adjustments for each string. Remember that movements of 4 semitones or more (up or down) may require a different string gauge to ensure instrument safety and optimal tension. Tuning beyond these recommended limits without suitable strings can lead to string breakage or damage to your guitar.

• String 7: Tune up 4 semitones to F1. (Caution: This is a significant upward adjustment. For string movements of 4 semitones or more, consider a heavier gauge string than your current one to maintain proper tension and prevent potential damage or breakage.)
• String 6: Tune up 2 semitones to F#3.
• String 5: Tune up 2 semitones to B2.
• String 4: Tune up 2 semitones to E3.
• String 3: Tune up 2 semitones to A3.
• String 2: Tune up 2 semitones to C#5.
• String 1: Tune up 2 semitones to F#5.
