This then was the situation until gestalt theory posed the radical question: is it at all the case that when I hear a melody I really hear the sum of individual notes at least as a primary basis? Is it not perhaps the other way around that what 1 have taken up in me the manner in which I perce­ive the single tone is that of a part determined by the structure of the whole? in other words what the melody gives me is not built up (by some added aids) secondarily out of the sum of the individual parts but what ta kes place in the indivi­dual part radically depends upon the whole. Is it not clear that the flesh and blood of a certain note in a melody depends upon the part it plays in that melody? that B as a leading tone of C is quite different from B as the tonic? that the role and function of data in a whole belong to the life and essence of the data?
