For Chinese culture (ritual, music) I always use the image of the iceberg—
to contrast the tiny little chunk that protrudes above the water (the conservatoire concert solos, and so on) with the vast unseen mass of popular culture below the surface—like temple fairs, shawm bands, household Daoists, spirit mediums…
Of course it applies widely to world cultures (cf. Italy). Even under the umbrella of WAM, there’s a fluid canon changing over time, with many outer rings; socially too, it’s not just the professional symphony orchestras. And Indian music is far more than sitar solos.
As to Daoism, it’s far more than the Daoist Canon and the White Cloud Temple; and far more than wise southeastern Daoists doing their mystical sublimation in the course of a jiao Offering. And Daoist ritual—over China, north China, Shanxi, north Shanxi, and even in the north-eastern central area of Yanggao county, is far more than the Li band!
Speech therapists too consider “the iceberg of fear“.
