Perhaps I misunderstand this due to lack of context, but since
capacitors in series are analogous to resistors in parallel, putting
50,000 small ones in series is equivalent to a single capacitor 50,000
times as small as each of the individual ones. Since the impedance of a
capacitor is inversely related to its size and directly related to
frequency, a *very* small one ought to have a horrendously large and
measurable impedance at low audio frequencies.  I've never seen such a
phenomenon myself.
