1. A circumferential row of vanes for a gas turbine engine, the circumferential row of vanes having non-uniform vane spacing and comprising:
a plurality of stator vanes arranged circumferentially about an inner ring, the plurality of stator vanes comprising:
a first group of stator vanes having a first spacing between adjacent stator vanes of the first group of stator vanes; and
a second group of stator vanes having a second spacing between adjacent stator vanes of the second group of stator vanes, wherein the second spacing is from two percent to eleven percent lesser than a nominal uniform vane spacing or from two percent to eleven percent greater than the nominal uniform vane spacing, the nominal uniform vane spacing being defined by a total number of the plurality of stator vanes.
