"Wishful Sinful" is a lush, romantic ballad from The Doors' 1969 album The Soft Parade, notable for featuring a solo by English horn player Champ Webb rather than the band's usual instrumental voices. Webb's English horn solo in A minor brings a classical, almost pastoral quality to the arrangement, the instrument's warm, reedy tone weaving through the song's orchestral texture with understated elegance. Written by Robby Krieger, the song is one of the most melodically beautiful compositions in The Doors' catalog, and the choice of English horn as the solo instrument reflects the album's ambitious expansion of the band's sonic palette. The English horn's melancholy timbre perfectly complements the song's yearning lyrics, its sustained, singing tone adding an emotional depth that a guitar solo might not have achieved. Paul Harris's orchestral arrangement surrounds the horn solo with strings that enhance the track's romantic atmosphere. Ray Manzarek's keyboard and Krieger's acoustic guitar provide gentle accompaniment, while John Densmore's brushwork maintains a subtle rhythmic pulse. The track demonstrates The Doors' willingness to subordinate their rock identity to serve a song's emotional needs, and Webb's solo is one of the most distinctive instrumental moments on the album.
