  Exact summatory functions that count the number of prime $k$-tuples up to
some cut-off integer are presented. Related summatory $k$-tuple analogs of the
first and second Chebyshev functions are then defined. Using a gamma
distribution hypothesis for prime powers, associated average summatory
functions are conjectured. With exact and average summatory functions in hand,
pertinent $k$-tuple zeta functions can be identified, and Perron's formula
allows the formulation of $k$-tuple analogs of explicit formulae. The $k$-tuple
zeta functions are then used to make some inferences about $k$-tuple primes.
