From Xenakis's UPIC to Graphic Notation Today sheds light on the revolutionary UPIC system, developed by composer Iannis Xenakis in the late 1970s. This digital innovation enables the transformation of drawings into musical compositions and continues to shape the world of contemporary music notation. Freely available in open access, this book provides unrestricted access to the historical origins of UPIC and its evolution into modern notation techniques. Richly illustrated, it reveals the unique fusion of image and sound. Through QR codes, readers can experience the compositions interactively.

IANNES XENAKIS (1922-2001) was not only a composer but also a visionary and a bridge-builder between music, mathematics, and architecture. Originally trained as an engineer in Athens, he developed innovative compositional techniques that integrate geometric and mathematical principles with music. His creation of the UPIC system established him as a pioneer of computer-assisted music, with an influence that extends into today's musical landscape. Often described as a "sound architect," Xenakis's unique approach and interdisciplinary works remain groundbreaking.
