The first jazz standard composed by a non-Latino to use an overt African cross-rhythm was Wayne Shorter's "Footprints" (1967). On the version recorded on "Miles Smiles" by Miles Davis, the bass switches to a tresillo figure at 2:20. "Footprints" is not, however, a Latin jazz tune: African rhythmic structures are accessed directly by Ron Carter (bass) and Tony Williams (drums) via the rhythmic sensibilities of swing. Throughout the piece, the four beats, whether sounded or not, are maintained as the temporal referent. The following example shows the and forms of the bass line. The slashed noteheads indicate the main beats (not bass notes), where one ordinarily taps their foot to "keep time."
