Hence S satisfies the conditions for being a [[periodic scale]]; note that the value is pitch given in units of octaves. This gives us our first definition of Fokker block.

Hence S satisfies the conditions for being a [[periodic scale]]; note that the value taken by S represents pitch given in units of octaves. This gives us our first definition of Fokker block.

By choosing various ''a''''k'' satisfying 0 ≤ ''a''''k'' < ''P'', for any Fokker block we may find the various [[Periodic scale #Rotations|rotations]], of the block. However, other choices lead to blocks which are not rotations of our initial block, but instead belong to [[dome]]s which are disjoint from the dome of the initial block. The collection of all Fokker blocks for any of the allowed values of the ''a''''k'' offsets is an ''arena''; a Fokker arena is defined entirely by its chromas.
