This unique Open A#maj7 tuning for Guitar emerges from an adventurous spirit of "experimenting and messing around," as described. It offers a rich and sophisticated sonic palette, moving beyond conventional open tunings.

Verbal Analysis

When strummed open, this tuning immediately presents a full and resonant A# Major 7th chord. This creates a lush, harmonically complex sound that is less common in standard open tunings, offering a unique tonal foundation. It can evoke moods ranging from contemplative and dreamy to elegant and jazzy. This tuning is ideally suited for genres that appreciate intricate harmonies, such as jazz, progressive rock, R&B, or even ambient and cinematic music. Its open, resonant quality also makes it excellent for slide guitar, drone-based compositions, or exploring fresh melodic and harmonic ideas.

Technical Analysis

The open strings are tuned to the following pitches:

• String 6: A#2
• String 5: F2
• String 4: D3
• String 3: F3
• String 2: A3
• String 1: F4

These notes collectively form an A# Major 7th chord, composed of the following intervals relative to A#:

• A# (Root - String 6)
• D (Major 3rd - String 4)
• F (Perfect 5th - Strings 5, 3, 1)
• A (Major 7th - String 2)

This tuning provides a robust and full voicing of A#maj7, featuring multiple octaves and repetitions of the 5th (F), which contributes to its rich and resonant character. The arrangement of notes allows for both deep bass tones and shimmering high harmonies.

Open Chords and Possibilities

The very act of strumming the open strings immediately yields a beautiful A#maj7 chord, offering an instant platform for musical creation. This foundation allows for:

• Movable Shapes: By barring across any fret, you can easily transpose the A#maj7 chord to other major 7th chords up and down the neck (e.g., barring at the 1st fret creates a Bmaj7 chord, at the 2nd fret a Cmaj7, and so on).
• Drone Tones: The repeated F notes (on strings 5, 3, and 1) and the root A# provide excellent opportunities for creating drone effects, especially useful in ambient or experimental music.
• Melodic Exploration: The specific arrangement of intervals, particularly the D3, F3, A3, F4, can inspire unique melodic lines and lead guitar phrases that leverage the open string harmonies.
• Chord Embellishments: Experimenting with adding other notes, such as a minor 7th (G#) or a 9th (C) to the open chord, can lead to even more complex and intriguing harmonies with minimal effort. This tuning is a playground for exploring voicings typically found in jazz and fusion contexts.

How to Tune Your Guitar to Open A#maj7

• String 6 (Low E): Tune down 6 semitones to reach A#2. (Note: Tuning down 6 semitones from standard E2 would theoretically result in A#1. Please ensure your tuner confirms A#2 as the target pitch for this string.) (This is a significant change: A different string gauge is advised for movements exceeding 4 semitones.)
• String 5 (A): Tune down 4 semitones to reach F2. (This is a significant change: A different string gauge is advised for movements exceeding 4 semitones.)
• String 4 (D): Keep as is; no change (0 semitones) to D3.
• String 3 (G): Tune down 2 semitones to reach F3.
• String 2 (B): Tune down 2 semitones to reach A3.
• String 1 (High E): Tune up 1 semitone to reach F4.

General Caution: Extreme tuning changes, particularly those exceeding +/- 4 semitones as seen on strings 6 and 5, can put excessive tension or looseness on your strings and the guitar neck. For optimal playability, intonation, and to prevent potential damage to your instrument, it is strongly recommended to consider using a different string gauge set specifically chosen for this tuning if you plan to use it frequently.
