from wikipedia...

"So What" is one of the best known examples of modal jazz, set in the Dorian mode and consisting of 16 bars of D Dorian, followed by eight bars of E♭ Dorian and another eight of D Dorian.^[1] This AABA structure puts it in the thirty-two bar format of American popular song.

The piano-and-bass introduction for the piece was written by Gil Evans for Bill Evans (no relation) and Paul Chambers. The distinctive voicing employed by Bill Evans for the chords that interject the head, from the bottom up three perfect fourths followed by a major third, has been given the name "So What chord" by such theorists as Mark Levine.

The same chord structure was later used by John Coltrane for his standard "Impressions".
