The linked article discusses the importance of pausing during practice, taking a short amount of time between "practice attempts."
"I always assumed that learning happened during the time my muscles were moving. The idea that some of the learning might take place in the time between practice attempts never occurred to me."
"The authors surmised that a 1-second break wasn’t enough time to process the information gleaned from each previous attempt, and get it into long-term memory. So even though they took the same exact number of practice trials as the other participants, the amount of learning the 1-second pausers were able to do between trials was reduced. Hence, the difference in performance during training, and their inferior performance on the test the following day."
"...found evidence suggesting that the performance improvement from trial to trial is due to the increased learning that can occur in the time following each error."
"So while it’s not clear if there’s a “perfect" pause length, 5 seconds seems like a good length to try. Better than 1 second, but not so long that it interrupts the flow of your practice session."
I think it can also be valuable to practice in short bursts, because we want to train ourselves to play an idea right away, without needing to get into a groove of some kind over a period of time in order to produce the desired result. Pausing is also an opportunity to check for unnecessary tension to be released.
