While there are many parallels between computing activities in musicology and those in other humanities disciplines, the particular nature of musical material and the ways in which this must be accommodated set many activities apart from those in text-based disciplines. As in other disciplines, early applications were beset by hardware constraints, which placed a premium on expertise and promoted design-intensive projects. Massive musical encoding and bibliographical projects were initiated. Diversification of hardware platforms and languages in the Seventies led to Walter B. Hewlett, the founder and director of the Center for Computer Assisted Research in the Humanities, holds degrees in physics, engineering science, and operations research in addition to a doctorate in music. He is the designer of the input, storage, and retrieval system for musical information that is in active use at CCARH for the encoding of the complete works of J. S. Bach, Handel, Mozart and other composers.
