In response to a comment on the R-symbol video (   • IPA Symbols for the R Sound  ) I not only explain a number of sounds and symbols for "R sounds" in the IPA, I give the names for them that tend to be the standard names for them. Note taken about people who have some degree of visual impairment, and I'll try to remember to do this in the future with more of the symbols I use - thanks for that comment!
