Finger Choreography

I am playing Ravel’s “Pavane” in orchestra.  It’s slow and  lovely and not terribly difficult.  I’m doing well until I get to the part where we’re playing pizzicato:

Strumming slowly and vibrating the top note.  It’s all working fine until I get to the last chord.  There’s an F sharp and I stop.  I’ve been happily playing by one finger on one note and barring two notes.  It works well when the two notes are in the same place on 2 strings, as in the 4th measure.  I barre the A-E with my one and play the C with my 2.  Now I have to play an F sharp, C and A.  I need to use 3 fingers.  It’s not difficult.  The trick is in the finger choreography.  I have to instruct my fingers, one finger at a time, where it is to go and when.   I have to determine which finger goes first and practice the motion  once I decide on the best and easiest way to get where I want to go.  Once this is done and I’ve practiced the motion many times, it feels natural and comfortable.    I sometimes forget that my fingers aren’t proficient at moving around the fingerboard.  They certainly are not as proficient as my brain.  I mean, I knew what those notes were and where they were on the instrument.  Why didn’t my fingers know too?   They just aren’t that smart and they need to be instructed.  I sometimes expect too much from them.   When they’ve had the choreography shown to them and they get a chance to rehearse, then they have learned and they know what to do.  It all works so well.
