A tuplet notation table record has two tuplet_portion records, one each for tuplet-actual and tuplet-normal subelement data. The foreign keys to these two records in the notation table are tuplet_actual_id and tuplet_normal_id, respectively.

A tuplet_portion record has:

• tuplet-number element data in table tuplet_number, foreign key tuplet_number_id
• tuplet-type element data in table tuplet_type, foreign key tuplet_type_id
• a list of tuplet-dot element data records in table tuplet_dot; foreign key in tuplet_dot is tuplet_portion_id
