Automated generation of contrapuntal musical compositions using probabilistic logic in Derive
Aguilera-Venegas, Gabriel; Galán-García, José Luis; Madrid, Rafael; Martínez, Antonio Manuel; Padilla-Domínguez, Yolanda; Rodríguez-Cielos, Pedro[et al.] (Elsevier (Mathematics and computers in simulation), 2010)
In this work, we present a new application developed in Derive 6 to compose counterpoint for a given melody (“cantus firmus”). The result is non-deterministic, so different counterpoints can be generated for a fixed melody, ... -
