Re Royal Road (J-Pop)
IV – V – iii – vi progression in Re major
Re Royal Road (J-Pop) — IV – V – iii – vi
The D IV–V–iii–vi Royal Road progression (G – A – F#m – Bm) dominates J-Pop and anime soundtracks through its sense of longing and forward motion. The Mixolydian mode colors the IV–V movement; Aeolian ties the iii–vi resolution together. Minor Pentatonic phrases work beautifully over the darker second half. With seventh voicings (GMaj7 – A7 – F#m7 – Bm7), the melodic depth matches the emotional weight of the genre.
Playing in Re major
D major is one of guitar's most resonant keys. The open D string acts as a droning root, and the open A string provides the fifth. This gives D-based strumming a wide, ringing quality that flatpicks and fingerpicks love. D is a beginner-level key on guitar because the open D and A strings provide a powerful bass foundation, and the open high E is the 2nd scale degree adding brightness. Beginners will find this key approachable since most chords use open voicings with minimal stretching.
Voice Leading
The bass line moves through G to A (ascending whole step), A to F# (descending minor third), F# to B (ascending perfect fourth). The root motion by larger intervals (fourths and fifths) gives each chord change a strong, decisive character. When the progression loops, the bass returns from B to G by major third.
Capo Transposition
To play in D using familiar open chords: capo 2 with open C shapes; capo 5 with open A shapes; capo 7 with open G shapes. Choose the capo position that gives you the voicings you prefer — lower capo positions produce a fuller sound, while higher positions create a brighter, mandolin-like timbre.
Scales for Soloing
D major pentatonic works because every note is either a chord tone or a safe passing tone — there are no avoid notes. For soloing, this means you can play freely without clashing. Over dominant seventh chords, D Mixolydian adds the flat seventh for an authentic blues-rock edge.
Strumming Pattern
Use D-DU-UDU at 100-120 BPM for a standard pop strum. Accent beats 2 and 4 for a backbeat feel. Vary dynamics between verse (lighter) and chorus (stronger) to build energy.
