I haven't done it in awhile, but need to work on it again since I plan on performing carnival of venice for a solo at school concert. 1) Exactly what syllables do you use? Tu-tu-ku? Ta-da-ka? Tu-tu-gu? I do tu-tu-ku, but wondering if anything works better for you people? 2) How come my tongue gets tired quickly when I triple tongue, then I cant do it and have to rest my tongue? How to make that not happen? Please tips. I can already double tongue pretty well, and my tongue never gets tired except triple tonguing. My tongue always gets tired with triple tonguing. Am I using it too harshly? What can I do to not make my toungue tired?
