If I understand your application is to cross reference for example a 
musical piece by instrumentation required, vocal parts required, 
liturgical season (Advent, Lent, Easter, etc.), possibly service setting 
(Holy Communion, Matins,  Vespers, etc.).

I would see a main table with listing each work with a unique id number 
assigned to it (key). The issue is how many tables will actually be 
needed for a good database design. Each table will have its own key with 
any foreign keys listed for cross referencing. The basic design rule is 
to enter data once and the keys establish the relation between the tables.

For a first pass at the design I would look at the data and cross 
referencing used in your manual card catalogue for data relationships.
