ABC or alphabet-based storytelling is the art of telling a story (or sometimes a poem) using each of the manual letters of alphabet. An Ameslan storyteller tells a story, using each manual letter in the alphabetical order from A to Z in ASL. For example, "A" for knocking on the door (which is very common), "B" for opening the door, "C" for shaking hands and so on. The storyteller can use various sequences, such as from A to Z, from Z to A, from AA to ZZ, or reversal.
Below is an example of the ABC story in ASL.
