sorry, it just seemed absurdly overspecific, wanting to know if r is pronounced like any of multiple pronunciations of r that you would have no reason to expect I had any familiarity with. It just seemed like a linguistic joke of some sort, like are you putting me on with this stuff? However - https://www.youtube.com/watch?v=lCScmkh8hQg
Thanks for the video! I often painted what one has to do with their vocal tract to illustrate how to create a certain sound, and I also use a finger in the mouth to show people how to pronounce the 'ch' in the german 'Ich', for if you try to pronounce the english 'sh' but have a finger in your mouth on the tip of your tongue you automatically produce the german 'ch'.
But instead of painting positions and stuffing things in mouths, one can also exchange information about this by just using text. That's what I did in my comment. So, no joke whatsoever. Just a specific question about how to pronounce a specific sound exactly.
