Pitch memory for one and for two successive tones was examined in two experiments which employed a method of adjustment procedure (Expt. I) and a recognition (four‐alternative‐forced choice) task (Expt. II). Frequency ratio of the two‐tone targets was either simple (a musical third or fifth) or complex. Time between target and comparison tone(s) was either silent or filled with two intervening tones. The memory difference limen (DL) for each of two tones is about 1.5 to 2.0 times larger than the DL for one tone. The DL for pairs of tones with complex frequency ratios is, under some circumstances, larger than for pairs of tones with simple ratios. For “good pitch discriminators,” the task must become more difficult before ratio complexity affects performance than is true for “poor pitch discriminators.” At least two skill components, frequency analyzing power and memory, are present in these tasks, and consistent individual differences occur for both.
