ABSTRACT:
A sport swing training aid for practicing the swing of a ball-hitting device including an elongated rod-like member having first and second ends, a grip on said first end, a stop on said second end, the rod-like member being hollow and internally corrugated and being capable of producing a tone as air passes through the member during the swinging thereof to produce a tone which varies in length and pitch in direct proportion with the velocity and duration of the movement of the ball-striking end as it is swung through a ball-striking zone, to thereby provide an audible feedback to the player as to the tempo and rhythm of the swing, and a slidable sleeve on the elongated rod-like member for travel between the first and second ends as the elongated rod-like member is swung, the stop and sleeve being of sufficient hardness to produce the feel and sound of the striking of a ball upon impact between the sleeve and stop.
