"Miles Davis's 'So What' is a landmark jazz composition from his 1959 album, Kind of Blue. The piece is known for its modal jazz structure, which emphasizes scales rather than traditional chord progressions. This innovative approach allows for greater improvisation and expression among musicians, making it a significant work in the jazz genre." "The song features a distinctive call-and-response pattern between the bass and horns, creating a conversational feel. Miles Davis on trumpet leads the ensemble, which includes notable musicians like John Coltrane on saxophone and Bill Evans on piano. 'So What' remains a quintessential example of modern jazz and continues to influence artists today."
