A turbomachine airfoil element includes an airfoil that has pressure and suction sides spaced apart from one another in a thickness direction and joined to one another at leading and trailing edges. The airfoil extends in a radial direction a span that is in a range of 2.85-3.15 inch (72.4-80.0 mm). A chord length extends in a chordwise direction from the leading edge to the trailing edge at 50% span and is in a range of 1.52-1.82 inch (38.6-46.2 mm). The airfoil element includes at least two of a first mode with a frequency of 506&#xb1;10% Hz, a second mode with a frequency of 1732&#xb1;10% Hz, a third mode with a frequency of 2268&#xb1;10% Hz, a fourth mode with a frequency of 4007&#xb1;10% Hz, a fifth mode with a frequency of 4851&#xb1;10% Hz and a sixth mode with a frequency of 6416&#xb1;10% Hz.
