Yo intento a rolly-polly mi "R"s. Es muy mal. Puede ayudar?
I am British (from liquidpoker.net/teamliquid) and have been trying to learn to roll/trill my Rs for several years now. I am slowly but surely getting better. At first I couldnt do it ONE BIT and it seemed like an impossible and hopeless challenge.
Perhaps if you have the time you would like to listen to my attempts and give your opinions and advice?
Really it is just a matter of time and practice, but I am curious to see any comments or experience you might have.
