Algorithmic Strings

Controlled randomness applied to the practice of the viola, violin and cello

Juan Ayuso Jiménez

"Hora lunga", scale of harmonics

Introduction:+Info

En esta aplicación aplicaremos la aleatoriedad para perfeccionar el fragmento final del primer movimiento de la sonata para viola sola de Gyorgy Ligeti(2001), donde se hace uso de la escala de armónicos naturales sobre la cuerda Do, la más grave del instrumento. Es a partir del análisis de este pasaje desde donde generaremos los ejercicios.

How to use:Tutorial

  1. Generate the scale of armonics, selecting the descending and jump probabilities on ‘Pitch generator module’.

  2. Create variations with the following modules: ‘Rhythm generator module’ and/or ‘Bowings generator module’. You can combine them (in this order). Each score is unique, so you can generate many of them with the same parameters.

  3. Generate the score on the buttons with in the modules. You can also download it in PDF or XML formats.
