Chapter 1: Introduction This book integrates three subject areas: Common LISP, Common Music, and algorithmic composition. The purpose of combining these three subjects into one book is to assist readers who are interested in composing music using computers. The author assumes the reader has very little experience with Common LISP or Common Music. Install Bsnl Evdo Modem In Windows 8. For this reason, usage and syntax of Common LISP and Common Music are explained through numerous carefully documented examples. The author assumes the reader has an understanding of tonal music theory and MIDI (The Musical Instrument Digital Interface) [IMA, 1983]. The majority of the examples in this book and the accompanying compact disc use MIDI.

Many wonderful compositions have been written over the years using Common LISP and Common Music. By making the details of how to use Common Music more approachable, the author hopes more people will be enticed to explore the potential of algorithmic composition.

1.1 Common LISP The programming language LISP derives its name from List Processing [Winston, 1989]. Forkplayer Torrent Tv Roku. Common LISP was developed in 1956 by artificial intelligence researchers Allen Newell, J.C.

Shaw, and Herbert Simon [Touretzky, 1990]. Since the early days of LISP, researchers have discovered the power of LISP's processing capabilities for music.

Music, a time-based art form, oftentimes is conceived as a succession of events. The events may be a series of pitches, articulation patterns, or a succession of rhythms.

Figure 1.1.1 depicts a pitch series that is accompanied by a list representation of that series. Each item in the list representation is called an element. Figure 1.1.1. 1.2 Common Music Common Music is an extensible programming environment for computer-based composition.

The development of Common Music began in 1989 by Heinrich Taube [Taube, 1989]. After several years of continuous evolution, Common Music was awarded first prize in the computer-assisted composition category at the 1er Concours International de Logiciels Musicaux in Bourges, France. Common Music is implemented in Common LISP and the Common LISP Object System [Keene, 1989]. Common Music's command line interface is called Stella.
