Standing on the shoulders of giants such as Bartok or Berio, I recently finished writing an ensemble piece titled Bastard Tunes. The piece was composed with the help of a machine learning system trained on transcriptions of Celtic music. The system produces short melodies that share many characteristics with the style it learned. But, with the possible exception of the fourth Bastard Tune, my piece applies more freedom in the way the system's output is used as compositional material. The piece will be premiered in a concert with other examples of music composed by and with computers.
This set displays a variety of approaches to graphic representation of sound. This group effort results in a full 'score' for a fairly extensive composition:
One of the foremost composers of the 20th century. Some recordings available on ubuweb. His folk songs are more then arrangements (and here is Voci a later piece which he subtitled folksongs 2). The series of sequenzas (e.g. viola, guitar) for solo instruments are a fantastic way to learn more about the instruments and imaginative ways to write for them. Coro integrates voices into the orchestra. His Sinfonia, particularly the 3rd movement, was discussed extensively.
Luigi Nono's composition for percussion and live electronics:
Edgar Varese Ionisation. And an article about the piece: Jean-François Charles - Organization of Scattered Timbral Qualities: A Look at Edgard Varèse's Ionisation.
