Why Concerto transcriptions? “ He was attracted to the rational tonal design and ritornello organization of the concerto that enabled the creation of unified, continuous instrumental movements on a hitherto unprecedented scale, avoiding, on the one hand, the tonal monotony and short-breathed sectionalism of, say, the variation set or the passacaglia, and on the other, the tendency, observable at times in the early toccatas –and even the early fugues- toward excessive variety and contrast at the cost of any sense of a compelling underlying unity.” -Robert L. Marshall, Eighteenth Century Keyboard Music
