All I have to do is get a whiff of an old 1920's-1930's film (or a film about that era) & I get all excited about the music. 

The 'Charleston' was danced to almost any Ragtime.  The steps got wilder with the 'Black Bottom' versions (visualize a cow trying to get unstuck from the riverbottom mud).  'Snake Hips' versions (including ones by Fats Waller and Duke Ellington) later evolved into some slower Blues Dances.  The 'Lindy' Charleston moved with the Lindy Hop into the 'Swing Jazz' era. 

ALL of these old tunes are listed as 'FOXTROT' on recordings! 

Many of these dance moves are still prevalent today... in HIP HOP! 

There's a performance of one "Snake Hips" in an old 1929 film ("Happy Days") that has always stuck with me since I saw it years ago.  The film is damaged, so bits of the music is missing. 

"Snake hips, shake your hips, follow thru to your fingertips, snake hips, do the wiggle waggle woo!" 

I have been playing along with "Snake Hips" on the fiddle, would seriously like to transcribe it, but haven't decided what it should be written in - seen ALL these kind of tunes written in 2/4, 2/2 AND 4/4 time, so I probably can't go wrong! 

When it comes to looking closer at the Charleston Rhythm and comping - I have found the best info from guitarists. 

Found an online educational source with at least some free content (the video I watched) from The University of Rochester.  The video is a lecture on The Charleston Rhythm - as pertaining to the Blues on piano. 

I've also learned some about where Blues and ragtime started to mingle for "Ragtime Blues" guitar in Piedmont - which seems to fall right in line with this topic.  The most upbeat 'Blues' I've ever heard.
