Sound Grammar is an album by jazz saxophonist and composer Ornette Coleman, recorded live in Ludwigshafen, Germany, on 14 October 2005. The album was produced by Coleman and Michaela Deiss, and released on Coleman's new Sound Grammar label. It was his first new album in almost a decade, since the end of his relationship with Verve in the 1990s. It features a mix of new and old originals (some of the latter given new titles).
Critics noted Coleman's unusual use of musical quotation: his solo on the blues "Turnaround" includes snatches of Richard Rodgers' "If I Loved You" and Stephen Foster's "Beautiful Dreamer"; even more unexpectedly, the theme of "Sleep Talking" begins with the same notes as Stravinsky'sThe Rite of Spring. Critical reception for the album was highly positive: it figured at or near the top of virtually every jazz magazine poll at the end of 2006, including Downbeat and Jazz Times.
In 2006, Sound Grammar received a Grammy nomination for Best Jazz Instrumental Performance. The following year, it won the 2007 Pulitzer Prize for Music.
