Fantasía para Guitarra y Ordenador
We recorded an original musical piece (lead guitar, rhythm guitar and drums) and used it as the input of our system. We produced an inspired composition and recorded it using Csound. The resulting audio was superposed on the original recording after the lead guitar stops playing (0:49) to emulate a jam session.
Melody Approximation
The melody is the essence of a musical piece... so we approximated the melody (extracted from audio) by basic mathematical functions: Legendre polynomials and Trigonometric-polyomial (trigonometric function and low order polynomials). The following examples (downloadable bundles) present a musical piece, the extracted melody, and the approximated melodies (for both approaches described); along with a brief summary of the results (time, fitness and a graphical representation of the approximation).
