The stiffened sole portion increases the frequency range of the golf club head by at least 300 Hz with an overall frequency of greater than about 3000 Hz. The stiffened sole portion provides a higher frequency sound with a minimal increase in the overall weight of the golf club head. In one embodiment, the stiffened sole portion increases the weight of the golf club head by less than 10 grams with the overall weight of the golf club head less than 220 grams. In operation, the golf club head with at least the stiffened sole portion impacts the golf ball to provide an aesthetically pleasing sound.
