INTRODUCTION Applications are widely studied in: Medicine Computer Science Physics Mathematics Research in artistic application is slim.

SOME BASIC MUSICAL TERMS Melody: A sequence of single tones, which a listener perceives as a single entity.

Pitch: The quality that makes it possible to judge sounds as “higher” or “lower. ”

Duration: How long a note lasts.

MUSIC PRODUCTION AND GENERATION

BRIEF HISTORY OF MUSIC GENERATION Australia’s Council for Scientific and Industrial Research (CSIR) installed a speaker to track the progress of running a program. Geoff Hill programmed a computer to playback a tune in 1951 Illiac Suite – Composed by a computer at University of Illinois at Urbana-Champaign, 1950 s Max Mathews develops MUSIC III, which synthesizes sounds on an IBM 7094 computer.

SOME PROBLEMS WITH QUANTUM COMPUTING APPROACHES Algorithms are different than in classical computing No cloning principle – A quantum system can not be replicated.

HOW DOES IT BECOME MUSIC?

IN CONCLUSION… There is still a lot to be discovered. Limitations exist Resources Money Knowledge
