The bright outsiders

These outsiders are stranger than the flat-side borrows: chords the key says should be minor, played major. The raised third works as a borrowed leading tone, so each one brightens the phrase and then pulls somewhere specific. The mechanism has a formal name, the secondary dominant, and a later lesson works it in full.

The whole palette in four chords: a bright outsider (III) walking to IV, then the borrowed iv coming home bittersweet. Radiohead's Creep runs this exact loop forever.
