Stomp progression

In music and jazz harmony, the Stomp progression is an eight-bar chord progression named for its use in the "stomp" section of the composition "King Porter Stomp" (1923) by Jelly Roll Morton. The composition was later arranged by Fletcher Henderson, adding greater emphasis on the Trio section, containing a highly similar harmonic loop to that found in the Stomp section. It was one of the most popular tunes of the swing era, and the Stomp progression was often used. Following the success of "King Porter Stomp", many other compositions were named after the tune, although many of these "stomps" did not necessarily employ the stomp progression. Magee (2014) describes a two-measure three-chord harmonic loop: F–F7—C7–C7. The progression () is based on the last section of the piece, bars 57 to 64 in the original sheet music for piano or the Fake Book lead sheet, where the chords for the last ten bars of the piece are: {|style="text-align:center" | | ||width=35px| G ||width=35px| ⁄ ||width=35px| G ||width=35px| ⁄ || | ||width=35px| D7/A ||width=35px| ⁄ ||width=35px| D7 ||width=35px| ⁄ || | ||width=35px| G ||width=35px| ⁄ ||width=35px| G ||width=35px| ⁄ || | ||width=35px| D7/A ||width=35px| ⁄ ||width=35px| D7 ||width=35px| ⁄ || | |- | | || G7 ||| ⁄ ||| G ||| ⁄ || | || | D/A || | A || | Bm || | D/A || | || | G || | ⁄ || | G || | ⁄ || | || | D/F || | Bm || | A || | D/A || | |- | | || | G || | G6 || | D/F || | A || | || | D9 || | ⁄ || | ⁄ || | ⁄ || | ∥ |} In pieces where the progression is repeated, this becomes something like: {|style="text-align:center" | | ∥: ||width=35px| G7 ||width=35px| G7 || | ||width=35px| D7/A ||width=35px| D7 || | ||width=35px| G7 ||width=35px| G7 || | ||width=35px| D7/A ||width=35px| D7 || | |- | | || | G7 || | G7 || | || | D7/A || | B7 || | || | E7 || | || | || | A7 || | D7 || | :∥ |} which is, ignoring the temporary tonicization of G, and treating the key as that of the trio and stomp sections, D: {|style="text-align:center" | | ∥: ||width=35px| IV7 ||width=35px| iv7 || | ||width=35px| I7() ||width=35px| I7 || | ||width=35px| IV7 ||width=35px| iv7 || | ||width=35px| I7() ||width=35px| I7 || | |- | | || | IV7 || | iv7 || | || | I7(_) || | VI7 || | || | II7 || | || | || | V7 || | I7 || | :∥ |} The last two measures contain the ragtime progression.
