By World War I, drum kits were often marching band-style military bass drums with many percussion items suspended on and around them. Drum kits became a central part of jazz music, especially Dixieland. The modern drum kit was developed in the Vaudeville era during the 1920s in New Orleans. In 1917, a New Orleans band called “The Original Dixieland Jazz Band ” recorded jazz tunes that became hits all over the country. These were the first official jazz recordings. Drummers such as Baby Dodds, “Zutty” Singleton and Ray Bauduc had taken the idea of marching rhythms, combining the bass drum and snare drum and “traps”, a term used to refer to the percussion instruments associated with immigrant groups, which included miniature cymbals, tom toms, cowbells and woodblocks. They started incorporating these elements with ragtime, which had been popular for a couple of decades, creating an approach which evolved into a jazz drumming style.
In 1918 Baby Dodds (Warren “Baby” Dodds, circa 1898–1959), playing on riverboats with Louis Armstrong on the Mississippi, was modifying the military marching set-up and experimenting with playing the drum rims instead of woodblocks, hitting cymbals with sticks (1919), which was not yet common, and adding a side cymbal above the bass drum, what became known as the ride cymbal. Drum maker William Ludwig developed the “sock” or early low-mounted high-hat after observing Dodd’s drumming. Ludwig noticed that Dodd tapped his left foot all the time. Dodds had Ludwig raise the newly produced low hats 9 inches higher to make it easier to play, thus creating the modern hi-hat cymbal. Dodds was one of the first drummers to also play the broken-triplet beat that became the standard pulse and roll of modern ride cymbal playing. Dodds also popularized the use of Chinese cymbals.
