The second movement of Maurice Ravel's second Violin Sonata (1922-1927) is titled *Blues* ([example performance](https://www.youtube.com/watch?v=UtP6g2bcwzc)). Wikipedia claims it is inspired by jazz and blues music, and that Ravel had first-hand knowledge of these styles e.g. from going to night clubs in New York with George Gershwin.

The violin part uses a lot of slow glissando's between adjacent notes, which vaguely resemble the bends that blues guitarists would do, and the piano part has a ragtime-style rhythm, but other than that, I don't hear much of a blues influence in it.

Does Ravel's *Blues* actually exhibit any of the more obvious aspects of blues — pentatonic scales, blue notes, micro-bends, dominant seventh chords, repeating a melody over the I and IV chord, the V-IV-I turn-around, 12-bar structure — in any meaningful way?

(And if it doesn't, is that because of a lack of understanding of the blues, or a reluctance to stray too far from the classical idiom, or the same attitude of the 19th-century "exoticism" craze which was far from authentic in its depiction of the music of the Orient and the Far East?)
