Description

This is a distinct 7-string guitar tuning, custom-designed by the user for an original song, and aptly named "Drop Amin7 Open". As the name strongly implies, when strummed open, this tuning immediately produces a full and resonant A minor 7 chord. It's built upon the foundational notes of A (root), C (minor third), E (perfect fifth), and G (minor seventh), spread across the seven strings.

Verbal analysis suggests a dark, somewhat reflective, yet powerful sound directly from the open position, making it highly suitable for atmospheric passages, introspective compositions, or genres requiring a deep, sustained harmonic foundation. The "drop" characteristic is evident in the lower strings, which extend the guitar's low-end capabilities for a heavier impact or more profound sonic texture. This open tuning significantly simplifies playing certain chord voicings, as the core components of the A minor 7 chord are already present in the open strings.

Technically, the tuning is: A1-E2-A2-C3-G3-C4-E4 (from the lowest 7th string to the highest 1st string). This arrangement provides multiple octaves of A, C, and E, which creates a rich, sustained harmonic foundation. The strategic doubling of notes (A1, A2; C3, C4; E2, E4) adds density and sustain to the open chord. Because the open strings form an Amin7, barre chords become exceptionally accessible: simply barre any fret across all (or the relevant subset of) strings, and you instantly have a minor 7th chord based on that fret's root note. For example, a barre at the 3rd fret would yield a Cmin7, and at the 5th fret, a Dmin7. This makes modal playing over minor 7th chords very intuitive. The wide tonal range, from a deep A1 to a bright E4, offers significant sonic possibilities for both rhythm and lead playing across various musical styles.

How to Tune

To achieve the "Drop Amin7 Open" tuning, we'll assume you're starting from a standard 7-string tuning (typically B-E-A-D-G-B-E from the lowest 7th string to the highest 1st string). Follow these specific adjustments for each string:

• String 7 (Original B): Tune down 2 semitones to A1.
• String 6 (Original E): Keep as is; no change (0 semitones) to E2.
• String 5 (Original A): Keep as is; no change (0 semitones) to A2.
• String 4 (Original D): Tune down 2 semitones to C3.
• String 3 (Original G): Keep as is; no change (0 semitones) to G3.
• String 2 (Original B): Tune up 1 semitone to C4.
• String 1 (Original E): Keep as is; no change (0 semitones) to E4.

Note on String Gauge: The maximum tuning adjustment in this setup is 2 semitones down or 1 semitone up. For changes exceeding 4 semitones in either direction (up or down), a different string gauge would generally be advised to maintain optimal tension and tone. For this specific tuning, the provided string movements are relatively minor, so your current string gauges should likely be suitable. Always check string tension and intonation after tuning to ensure proper playability and sound.
