C# Royal Road (J-Pop) — IV – V – iii – vi
The C# IV–V–iii–vi Royal Road progression (F# – G# – Fm – A#m) dominates J-Pop and anime soundtracks. Starting on the subdominant creates a sense of longing and emotional journey. With seventh chords (F#Maj7 – G#7 – Fm7 – A#m7), it gains even more melodic depth.
