Even now, all this time after the years I spent immersing myself in the wild shawm and percussion playing of the Hua family band in Yanggao (“Ming-dynasty bebop”), I still regularly find myself tapping out the slow 8-beat drum pattern that accompanies the opening sequence of melodies in their ritual suites.
Within a slow 8/4 metre, the recurring pattern on the drum is punctuated by one gong stroke and four cymbal clashes every measure. The drum pattern may be considered as beginning on the 3rd beat of the bar, with a little syncopated motif “calling for the beat” (jiaoban 叫板) alerting the gong player to sound the coming downbeat. Hua Jinshan often varies the first two beats of the bar. I’ve only attempted a rough rhythmic depiction of the drum part, refraining from an exhaustive notation of all the varied techniques, with rim-shots, single- and double-stick notes, and damped notes—here the slur sign denotes a roll before the beat:
The pattern is quite fixed, with only occasional minor variants—though there is a certain variation between different drummers.
An easily-followed instance is the opening of the Da Yanluo suite, whose melodies I analyse in detail—with video—in Dissolving boundaries. For the gradual accelerando and the cumulative effect of the pattern, do get to know the two versions of Shuilongyin on the CD Walking shrill (one of them also on the playlist in the sidebar, #5, with commentary here). Once you have the metrical framework in your bones, you can admire the long melodic phrases and the way their own syncopated rhythms constantly tug at the metre. This is AMAZING music—Trust Me, I’m a Doctor.

Meanwhile household Daoists take part in the same rituals; and though their instrumental repertoire is quite different, their use of percussion has certain similarities. As the first beat of the bar approaches (here it is the cymbal player who sounds the downbeat), drummers like Li Manshan play a syncopated motif similar to that of the shawm bands—and then tends to leave the downbeat to the cymbals (for the subtleties of the variants, see here). This example, from the slow, mournful hymn Diverse And Nameless Are The Bitter Roots, shows both the drum patterns and the yaoshuan syncopation on cymbals at cadences:
In my film (from 22.04) you can find clear examples in the Hymn to the Three Treasures, with the late Yuan Gaoshan on drum.
Along with memorizing the vocal texts and melodies of the liturgy, such unwritten rules are a substantial aspect of the nitty-gritty of what household Daoists have to learn in performing ritual.
