La Royal Road (J-Pop)
IV – V – iii – vi progression in La major
La Royal Road (J-Pop) — IV – V – iii – vi
The A IV–V–iii–vi Royal Road progression (D – E – C#m – F#m) 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 (DMaj7 – E7 – C#m7 – F#m7), the melodic depth matches the emotional weight of the genre.
Playing in La major
A major is a rock and blues cornerstone. The open A string delivers a strong root, while both E strings ring as the fifth. Classic A-D-E progressions practically play themselves with open cowboy chords. The open high E is the fifth, reinforcing power. A is a beginner-level key on guitar because the open A string is the root and the open E strings provide the fifth above and below, creating a massive low-end anchor. Beginners will find this key approachable since most chords use open voicings with minimal stretching.
Voice Leading
The bass line moves through D to E (ascending whole step), E to C# (descending minor third), C# to F# (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 F# to D by major third.
Capo Transposition
To play in A using familiar open chords: capo 2 with open G shapes; capo 5 with open E shapes; capo 7 with open D 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
A 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, A 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.
