When a certain note in a passage gives you difficulty, start the passage with the problem note, as if there were no preceding notes eventuating into it*. So often it is the sequence of events and their context which creates the apparent difficulty. Taken out of context the problem note is seen as being just a note, like any other on the keyboard, played with one of the ten “usual” fingers.
* In computer program it is like putting in a “breakpoint”*. (From Google Chrome). In software development, a breakpoint is an intentional stopping or pausing place in a program, put in place for debugging purposes. It is also sometimes simply referred to as a pause. More generally, a breakpoint is a means of acquiring knowledge about a program during its execution.
