When you double tongue using T and K, do the notes sound the same? Lets say you play a Bb using T and play the same thing using K. Will there be any noticeable difference in sound? Or will both notes still sound the same? Are these good exercises to learn double tonguing if you don't know how to do it? http://www.thetrumpetblog.com/wp-content/uploads/2011/01/Double-Tonguing-Exercises.pdf I'm about to head off into high school so I gotta know these things. Thanks!
