I've danced extensively, and tap can be brutal for the sheer number of steps you need to remember. Other dance disciplines, like ballet, tend to chunk sets of smaller movements into a larger, named one, so once you learn those sequences, it's easy to learn and recall longer routines. The way ballet is put together aligns with advice from brain science about chunking objects in memory for better recall. But tap has few of those chunked sequences, other than the "time step," so you're left trying to parse long strings of very finite instructions. "Left ball right heel left flap ball change..." Personally I found it overwhelming and didn't pursue tap into the most advanced levels for that reason.

Aside: it seemed like neurotypical folks struggled less with tap than I did as an AuDHD person, so tap may land differently with different neurotypes.
