Verbal Analysis: Yasashisano Riyuu (Reason for Kindness)

This distinctive custom tuning, originally named "Yasashisano Riyuu" (Reason for Kindness), offers a rich and deeply atmospheric sound. With its open C Minor 9 chord structure, it immediately evokes a sense of introspection, melancholy, or sophisticated jazz harmony. The substantial drops in pitch on the lower strings create a powerful, resonant bass foundation, perfect for crafting immersive soundscapes, intricate fingerstyle pieces, or blues and jazz-influenced compositions. The higher strings are critical, introducing the minor 7th and minor 9th intervals that give this tuning its complex and 'velvet' harmonic character, encouraging exploration of darker, more nuanced voicings.

Technical Analysis: Open C Minor 9

This is a custom tuning designed for a standard Guitar. It is specifically arranged to produce an open C Minor 9 chord. The open string notes, from the lowest (thickest) to the highest (thinnest), are:

• String 6: C2
• String 5: G2
• String 4: D3
• String 3: G3
• String 2: A4# (Bb4)
• String 1: D5# (Eb5)

When strummed open, these notes collectively form a full C Minor 9 chord (C - D - Eb - G - Bb). Analyzing the intervals from the lowest C: we have the Root (C), Perfect 5th (G), Major 2nd/9th (D), Perfect 5th (G - an octave higher than the 5th string), Minor 7th (A# / Bb), and Minor 3rd/Minor 10th (D# / Eb). This particular voicing provides a comprehensive and harmonically dense sound, allowing for complex musical ideas right from the open position.

Open Chords and Reachable Voicings:

The primary and most immediate open chord available is a rich C Minor 9. This tuning makes it incredibly easy to transpose this chord up the neck; simply barring all strings at any given fret will yield another minor 9 chord. For example:

• Barre at the 3rd fret: Eb Minor 9
• Barre at the 5th fret: F Minor 9
• Barre at the 7th fret: G Minor 9

Beyond full barre chords, the arrangement of the lower strings (C-G-D-G) offers a versatile foundation. This quartet can easily support G power chords (G-D-G) or various sus2 voicings by simply muting the higher strings or employing partial barrés. The resonant interplay between the open D3 and G3 strings, combined with the characteristic minor 7th (A#) and minor 3rd (D#) on the higher strings, encourages fluid arpeggiation and melodic lines that inherently fit within the minor harmonic context.

How to Tune: From Standard E Standard Tuning (E A D G B E)

• String 6 (Low E): Tune down 4 semitones to C2. (Note: Tuning down 4 semitones is a significant pitch change; while achievable with standard string gauges, you might consider a heavier gauge string for improved tension and tone stability, especially if this is a long-term tuning.)
• String 5 (A): Tune down 2 semitones to G2.
• String 4 (D): Keep as is; no change (0 semitones). This string remains at D3.
• String 3 (G): Keep as is; no change (0 semitones). This string remains at G3.
• String 2 (B): Tune down 1 semitone to A4# (Bb4).
• String 1 (High E): Tune down 1 semitone to D5# (Eb5).
