What is the proper or usual term that names the following problem in piano playing?
Problem: The finger, after striking a note, does not release the key on time but overstays (typically by about 50 to 100 milliseconds). As a result, the note sounds longer than it should and bleeds into the beginning portion of the next note.
The person in the video calls it "finger pedaling." But he is referring to it as a technique, something you do on purpose, for an effect:
I am talking about overlaps that happen unintentionally (because you are being sloppy), a problem.
(I am finding that my generic descriptions, e.g. "unintended overlaps," are no proper search terms and don't turn up anything useful. Once I know the term, I may come back here and ask substantive questions, e.g. how to solve.)
Add later: Just so I don't mislead, I should add that the unintended overlaps happen to me even when I am not being sloppy but on the contrary am trying my best not to have them, especially when going from finger 4 to 3.
