Question : How to write a correlated query between tables

I have two tables in sql server 2008.  One is a customer table and the other is a customers spouse table. Each customer has notes which I need to ensure also exist on the spouse note. That is I need ensure the spouse has all the notes that were added to the customer record.  How do I write a query to show me spouses which dont have the note of the related customer? Of course then I need the note and the spouse ID so I can add them to the database.

The spouse and the customer are linked (ie there is a customer id on the spouse table pointing back to who their spouse is).  I believe the technique for this is to use a correlated query but im not sure.  Below are the two tables (if you cant see them because of formatting I've uploaded an excel file with the tables):

CUSTOMER TABLE            
Cust ID      customer                 Note
1               John                    Email Contact Only
1               John                    Phone After 5pm
1               John                    Don’t Snail Mail
2               Peter                   Don’t Snail Mail
3               Eddy                   Call on Cell Phone
3               Eddy                   Forward to VP
4               Tim                     Email Contact Preferred
4               Tim                     Phone After 5pm

CUSTOMERSPOUSETABLE                  
CustomerSpouseID          SpouseName         RelatedtoCustomerID                  Note
57                                  Jane                        1                                             Phone After 5pm
58                                  Mary                       2                                             NULL
59                                  Fran                        3                                             Forward to VP
60                                  Barbara                   4                                             Email Contact Preferred
