This module is a continuation of the previous module on composing a cantus firmus. In this module, we will continue our algorithmic approach to generating a well-formed cantus firmus based on clearly defined rules and guidelines. In the previous module, we created a function that was responsive the following principles: We nested the random_note() function […]
