Hmmm good question. As I think about it, the "stutter" tends to be more common in a run leading up to the start of a phrase. Let's see, how do I describe it... Say you have a song and the lyric is "Because it's now or never," and "now" is on the downbeat of the measure. The notes for "Because it's" leading up to that tend to cause a stutter more than others. Measure: 1 2 3 4 Subdivided into eighths: 1&2&3&4& Phrase: &4&1 2 3 4 Downbeat on: 1 Stutter at the start of: &4&
