BF#BDAC# | BG♭BDAD♭ B F# B D A C# - Guitar tuning, chords & scales
Verbal Analysis
The "Angular B-Drop" tuning plunges your guitar into a deep, resonant sonic landscape, immediately evocative of its described 'Math Rock' origins. With its lowest string hitting a thunderous B1, this tuning offers a heavy, almost industrial foundation, while simultaneously opening up unexpected melodic and harmonic possibilities across the higher strings. The significant downtuning across all strings gives the guitar a slacker feel and a darker, more aggressive timbre, perfect for intricate riffing and complex, shimmering chords characteristic of the genre. It feels both grounded and expansive, creating a sound that can be both crushing and surprisingly delicate, encouraging exploration beyond conventional fretboard patterns.
Technical Analysis
This tuning, applied to a standard 6-string guitar, establishes the open notes as B1 F#3 B2 D3 A3 C#5. This is a highly irregular and wide-ranging tuning, setting it apart from more common drop or open tunings.
- The lowest three strings (6th, 5th, 4th) are tuned to B1 F#3 B2. This combination immediately presents a powerful B5 (B power chord) spanning a significant two-octave range, with the F#3 acting as the fifth above B1. This creates a full, weighty low-end ideal for impactful, driving rhythms.
 - Moving to the middle and high strings (3rd, 2nd, 1st), we find D3 A3 C#5. Notably, these three strings form a perfect D Major triad (D-A-C#), albeit with the highest C# an octave above standard. This juxtaposition of a low B5 power chord and a higher D Major triad suggests a rich, potentially polytonal character, ripe for the harmonic adventurousness found in math rock.
 - The intervals between adjacent strings are exceptionally wide and varied:
- String 6 (B1) to String 5 (F#3): An enormous perfect fifth interval spanning two octaves. This creates a very open, ringing quality.
 - String 5 (F#3) to String 4 (B2): A perfect fourth (F#-B) but dropping an octave, again contributing to the expansive feel.
 - String 4 (B2) to String 3 (D3): A minor third.
 - String 3 (D3) to String 2 (A3): A perfect fifth.
 - String 2 (A3) to String 1 (C#5): A major third interval spanning two octaves.
 
 
The overall open tuning combines the low root and fifth of B with the major harmony of D. This blend of heavy, low-end power with bright, clear higher-register major chords provides a versatile canvas for intricate arpeggios, dissonant voicings, and the signature angular melodies of math rock. The wide intervallic jumps between strings will require a different approach to chording and scale navigation, opening up unique voicings that are difficult or impossible in standard tuning.
Open Strings
The "Angular B-Drop" tuning for Guitar sets the open strings as follows (from lowest to highest):
- 6th String: B1
 - 5th String: F#3
 - 4th String: B2
 - 3rd String: D3
 - 2nd String: A3
 - 1st String: C#5
 
How to Tune (from Standard EADGBe)
To achieve the "Angular B-Drop" tuning, adjust your guitar strings from standard EADGBe as described below:
- 6th String (Low E): From E2, tune down 5 semitones to B1.
 - 5th String (A): From A2, tune down 3 semitones to F2.
 - 4th String (D): From D3, tune down 3 semitones to B2.
 - 3rd String (G): From G3, tune down 5 semitones to D3.
 - 2nd String (B): From B3, tune down 2 semitones to A3.
 - 1st String (High E): From E4, tune down 3 semitones to C#4.
 
Important Note on String Gauge: This tuning involves significant drops for most strings. The 6th and 3rd strings are tuned down 5 semitones, and the 5th, 4th, and 1st strings are tuned down 3 semitones. Such substantial detuning, especially beyond 4 semitones, often benefits from using a heavier gauge string set to maintain optimal string tension, intonation, and playability, preventing the strings from becoming too loose or buzzing.
