This pattern is a staple of mine, that I would use a lot when playing reels. The “Dum Dum Ta” part should be used sparingly, and is good for emphasizing the end of a lower key part of a tune. The below clip is a slow version of the pattern
<span style="text-align: center;">Dum Ta Dum Ta Dum Ta Dum Dum Ta (repeated 4 times) </span>
Then part two is the above repeated four times.
