Early technique and instrumentation
The first true jazz drummers had a somewhat limited palette to draw on, despite their broad range of influence. Military rudiments and beats in the military style were essentially the only technique that they had at their disposal. However, it was necessary to adapt to the particular music being played, so new technique and greater musicianship evolved. The roll was the major technical device used, and one significant pattern was simply rolling on alternate beats. This was one of the first "ride patterns", a series of rhythms that eventually resulted in a beat that functions in jazz as the clave does in Cuban music: a "mental metronome" for the other members of the ensemble. Warren "Baby" Dodds, one of the most famous and important of the second generation of New Orleans jazz drummers, stressed the importance of drummers playing something different behind every chorus. His style was regarded as overly busy by some of the older generation of jazz musicians such as Bunk Johnson.
