Long Live the Beat 2: Encore · audio sketch

118 years of life expectancy, played by the band

Each year of CDC NCHS data is one bar of a 12-bar blues in C. Life expectancy picks the melody note, snapped to the chord so it never plays a wrong note. The death rate sets the tempo and how hard the drums work. The instruments change with each era's zone, and 1918 drops to a solo piano.

The x-axis is song time, not calendar time: slower bars take more room and the 1918 breakdown plays at half tempo. Gold dots are launch runs (life expectancy up 3+ years); ringed dots are stop-time bars (down 2+ years). Click anywhere to jump there. Song length 4:14.
