"Panama" (sometimes incorrectly called "Panama Rag"[1]) is a jazz standard. It is by William Henry Tyers, originally entitled "Panama, a Characteristic Novelty",[2] published in 1912.[3]
The original tango or maxixe rhythm is usually discarded in favor of 4/4 time, but can still be detected in some versions, such as the early recording by Johnny DeDroit's Band.
Some later generations have sometimes confused it with a totally different piece of a similar name, a ragtime number composed by Charles Seymour in 1904 called "Panama Rag".[4] This lesser known number has been recorded by the New Orleans Ragtime Orchestra and was reportedly played by Buddy Bolden when the tune was new, but is rather obscure and far from a standard.
