Jelly Roll Morton demonstrates the creation of
Tiger Rag (describing early 1900s)

Now Jazz Started in New Orleans, and this Tiger Rag happened to be transformed from an old Quadrille that was in many different tempos.  An I'll no doubt give you an idea of how it went:

This was the introduction meaning that everyone was supposed to get their partners.

"Get your partners, everybody get your partners!"  People would be rushing around the hall getting their partners.  Maybe, have maybe a five minutes lapse until that time, and then they started over again and that was the first part

And the next strain would be a waltz strain.

That would be the waltz strain.  Also they would have another strain that comes right beside it.  Mazooka [Mazurka] time.

Of course, that was that third strain.  And of course they have another strain, and that was in a different tempo.  That’s a two-four time.

Of course they had another one.  Yeah!

Now I will show you how it was transformed.  It happened to be transformed by your performer at this particular time.  Tiger Rag [for your approval?].  I also named it, came from the way that I played it by making the "tiger" on my elbow.  I also named it, a person said once "It sounds like a tiger hollering."  I said "Fine," to myself. I said, "That's the name".  So I'll play it for you.
