Halim Abdul Messieh El-Dabh (Arabic: حليم عبد المسيح الضبع, Ḥalīm ʻAbd al-Masīḥ al-Ḍabʻ; born March 4, 1921) is an Egyptian American composer, performer, ethnomusicologist, and educator, who has had a career spanning six decades. He is particularly known as an early pioneer of electronic music. In 1944 he composed one of the earliest known works of tape music, or musique concrète. From the late 1950s to early 1960s he produced influential work at the Columbia-Princeton Electronic Music Center.
El-Dabh was born and grew up in Sakakini, Cairo, Egypt, a member of a large and affluent Coptic family that had earlier emigrated from Abutig in the Upper Egyptian province of Asyut. The family name means "the hyena" and is not uncommon in Egypt. In 1932 the family relocated to the Cairo suburb of Heliopolis. Following his father's profession of agriculture, he graduated from Fuad I University (now Cairo University) in 1945 with a degree in agricultural engineering, while also studying, performing, and composing music on an informal basis. Although his main income was derived from his job as an agricultural consultant, he achieved recognition in Egypt from the mid- to late 1940s for his innovative compositions and piano technique.
It was while he was still a student in Cairo that he began his experiments in electronic music. El-Dabh first conducted experiments in sound manipulation with wire recorders there in the early 1940s. By 1944, he had composed one of the earliest known works of tape music or musique concrète, called The Expression of Zaar, pre-dating Pierre Schaeffer's work by four years. Having borrowed a wire recorder from the offices of Middle East Radio, El-Dabh took it to the streets to capture outside sounds, specifically an ancient zaar ceremony, a type of exorcism conducted in public. Intrigued by the possibilities of manipulating recorded sound for musical purposes, he believed it could open up the raw audio content of the zaar ceremony to further investigation into “the inner sound” contained within.
