Hello everybody. Over the past few months I have been heavily refining my playing, and I've recently been working really hard on double tounging. I can do it very well for a few notes, but when I do more than a few I just seem to trip on my tounge and it blends into a single note. The funny thing is, over my time working on exercises for multiple tounging, I've only gotten worse. I've tried slowing down the tempo, but it only seems to make it more difficult. What am I doing wrong, and how can I fix this? Any tips are greatly appreciated.
