Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Question ###
What is the average size (cents) with an interval of major third and size (steps) more than 5

SELECT AVG(size__cents_) FROM table_name_33 WHERE interval_name = "major third" AND size__steps_ > 5
