Between the single unit and inseparable mass of texture lies 'many'. Many occurs at a largest scale where the form of individual components are still discernable. Thus content plays a stronger role in many than in pattern or texture.
An characteristic of 'many' to varying degrees is the element of surprise; of seeing so many things in one place, such as the flocking of flamingos in crater lakes; the clustering of monarch butterflies on oyamel trees in Mexico; or the human pilgrimage of Kumbh Mela. Large numbers imply a great occasion or event.
The conventional approach to composing with 'many' is to frame within the boundaries of the aggregation to imply that there is no limit to its extent.
