An aid for teaching players specific proper tennis grips is provided in two form factors. The aid can be provided in a wrap or a band form factor. The aid comprises a reference for each of the following grips: Continental, Eastern, Semi-Western, and Western. The references are spatially located on the aid, such that when installed onto a neck of a tennis racket, each reference aligns with the "V" formed between player's thumb and forefinger when holding the racket with the respective grip. The references can be color coded, provided in differing fonts, include unique graphical representations, and the like.
