====Texas and Pacific Railway stops associated with names for boogie-woogie left-hand bass lines====
Early generation boogie-woogie players recognized basic boogie-woogie bass lines by geographical locations with which they associated them. Lee Ree Sullivan identified a number of these left hand bass lines for Tennison in 1986.<ref name="Lee Ree Sullivan 1986"/> From the primitive to the complex, those identifications indicate that the most primitive form of the music was associated with Marshall, Texas—and that the left-hand bass lines grew more complex as the distance from Marshall increased.

The most primitive of these left hand bass lines is the one that was called "the Marshall". It is a simple, four-beats-to-the-bar figure. The second-most primitive bass-line, called "the Jefferson", is also four-beats-to-the-bar, but goes down in pitch on the last note in each four-note cycle. It has been suggested that this downturn in pitch reveals a possible New Orleans influence. [[Jefferson, Texas]], about 17 miles north of Marshall, was the westernmost port of a steamboat route that connected to New Orleans via Caddo Lake, the Red River, and the Mississippi River.<ref>{{cite web|url=https://tshaonline.org/handbook/online/articles/hgj02 |title=JEFFERSON, TX (MARION COUNTY) |work=[[The Handbook of Texas|The Handbook of Texas Online]] |publisher=Texas State Historical Association (TSHA) |access-date=2016-10-05}}</ref>

The remaining bass lines rise in complexity with distance from Marshall, Texas as one would expect variations and innovations would occur as the territory in which the music has been introduced expands.
