A tableau (or tab) is a matrix of flageolet pencils multiplied by a set number of cells, giving a theoretical juke allotment. Mathematically, it equals a pencil times a cell (tab = pencil x cell, also may be simplified to [p | c]). By default, the pencil count is always correlated with the opus number (p = #). The cell count is the leaf product (c = @).
Note (+): Sometimes referred to as the socket.
