Hey guys, I made a video on you can use groupings as a cool effect, if you have make fill ins. Instead of playing notes, use the rhythmic effect of a different grouping and try to move the 16th note group around, to another starting point. When I figured this out it changed my playing, and my abilities to makeup different types of fill ins, so I want to share a bit with you. In the video there are examples on how you can group them in 5 instead of the often used 4 grouping. Also you can see the facilities at the amazing Royal Academy of Music in Aalborg, Denmark.
