This invention embodies golf clubs and heads providing visual, auditory, and/or tactile aids useful to a golfer in determining whether a golf ball has been accurately struck. The head of the golf club is designed to produce a fundamental musical tone upon impact with a golf ball at the sweet spot of the club face. When a golf ball is struck at areas outside of the sweet spot, the head produces audible harmonic overtones that resonate above the fundamental pitch. Furthermore, the shaft of the golf club is preferably made from a resonant material that is attached to the head at a vibratory node of the head such that when a golf ball has been accurately struck using the sweet spot of the club face, no harmonic vibrations are transferred along the shaft to the grip.
