Is anyone aware of interesting research or work investigating what a just-noticeable difference for repetition in music might be?
Say I have a sequence that contains 100 events, repeats every 45 seconds and which is generally noticeable as a repeated sequence after 2 repetitions. There must be a threshold to the length of the sequence, or the number of events, where the sequence would not feel like a repetition, even after it was repeated 10 times, right?
I would think a 3 hour long sequence already would need more repetitions to be noticeable as a repetition, maybe it’s too long to be noticeable at all with the right balance of events and sound content…
I saw Jorrit Dijkstra give a masterclass where he was working with layering improvised loops that were a few minutes long. He knew exactly where he was in the loop and would make magic happen when suddenly his playing would align perfectly with the ghost saxophonist – because the loop was so long as to not be apparent as a loop, sometimes even within the entire length of the improvisation it was hard to pick out the edges of the loop.
This seems like a musically useful thing to study – maybe there is already useful research?
