The most romantic jazz ballads, nocturn or blues

• "Ming" - World Saxophone Quartet from the "Revue" album - sublimely beautiful ballad. Written by David Murray in honor of his beautiful wife.
• "Naima" - John Coltrane Quartet from "Giant Steps" - Another sublimely gorgeous love ballad, in this case written by John Coltrane for his wife.
• "Idle Moments" - Grant Green from "Idle Moments" - Can't think of another jazz guitar ballad I find more affecting.
• "Autumn Leaves" - from "Somethin' Else" by the Cannonball Adderley Quartet with Miles Davis. Miles' muted trumpet solo in this tune is a masters class in how to play pretty.
• "Afro Blue" - from Oscar Brown Junior's "Sin and Soul" - Ballad singer par excellence.

Art Pepper! Many good suggestions here, but AP on a ballad is devine, especially his late career stuff. Try Straight Life, Patricia, Our Song or Nature Boy.
