Some time ago, I came across this article on Classical Guitar Corner on Spot Practice that I found very helpful. Dave describes Spot Practice as:
‘Spot practice is a lot like slow practice, but with one important difference: while slow practice reduces the tempo to give your fingers more time to make the movements they need to make and to identify problems you couldn’t notice when playing at faster tempos, spot practice removes tempo as a factor altogether.
Here’s how spot practice works: when you get to a tricky spot in a passage (something slow practice should have helped you identify as a trouble passage!) we want to STOP. Completely pause right at, say, that difficult left-hand shift. Then take it step by step, without the tempo: (1) Determine exactly the movements your fingers need to make to get from where they are to where they need to go; (2) Begin to prepare your fingers over the strings they are going to go; (3) Shift positions and carefully and in a relaxed manner place your fingers to land the shift; (4) Repeat. That’s it! The point here is to give your fingers the time they need to make that shift accurately’.
