There are 2 schools of thought here and you decide what is the aim of any session.

In some lessons Lisa stresses the need to place fingers correctly and check the strings all ring out cleanly.

But in some lessons the stress is keeping up with the pace of chord changes and ignore the inevitable duff notes.

So some practice to make clear chords and changes at whatever speed you find you are capable of if using the metronome.

In another part try and see how many chord changes between 2 chords you are able to make in 60 secs. [br]In one you will see the muscle memory increase in forming the chord

In the other you will have a clear measure of chord change speed increasing as your dexterity across the fretboard improves. [br]It never has to be just one or the other.
