I'm re-naming this Thread: "They Scowl at my Growl, and Snicker at my Flutter". Thanks to brekelefuw I can edit this thread with the proper terminology. I can roll my R's when I speak Spanish, but I can't get a good Flutter Tonguing on the horn. I can start a flutter but can't sustain it. I need all the suggestions, tricks, technique, method, and whatever you can offer to help me get a good sustainable Flutter. Include your Growling technique too if you will. Do you Growl something like a Buddist monk, or to sing/speak something that sounds like vocalizing without moving your lips?
