AI ANSWER
For a Beatles-style ballad, try C major, G major, or A major with progressions like I–V–vi–IV (C–G–Am–F) or I–IV–V (C–F–G). These keys feel warm and open. Use major 7th chords like Cmaj7, Fmaj7, and Gmaj7 for that dreamy, sophisticated sound the Beatles loved in songs like Let It Be and The Long and Winding Road.
