A turbomachine airfoil element includes an airfoil having 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 0.60-0.70 inch (15.3-17.8 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 0.90-1.00 inch (22.9-25.5 mm). The airfoil element includes at least two of a first mode with a frequency of 5327&#xb1;10% Hz, a second mode with a frequency of 8393&#xb1;10% Hz, a third mode with a frequency of 16289&#xb1;10% Hz, a fourth mode with a frequency of 25049&#xb1;10% Hz and a fifth mode with a frequency of 27423&#xb1;10% Hz.
