Time Judgement Development Exercise

Using a digital delay unit and a recording of a high- pitched drum sound (or a drum machine):

1. Route a non-delayed signal to one loudspeaker, and a delayed signal to the other loudspeaker.

2. Delay the signal, perform many repetitions of the sound, using time-increments that are easily recognizable (always move by the same time- increment unit, such as 100 ms, within a given listening session).

3. As confidence is obtained in being able to accurately judge certain time units increases, move to smaller and larger time units, and repeat the procedures of step 2.

4. When control of time relationships is accurate within certain defined limits and the reader is confident in this ability, test that accuracy by routing both the direct and delayed signals to both loudspeakers (or to a single loudspeaker).

5. Continue to work through many repetitions of time increments in a systematic manner, comparing the qualities of the time relationships of each listening, to previous and successive material, in a logical sequence (a suggested pattern or sequence: 150 ms, 125 ms, 100 ms, 75 ms, 125 ms, 150 ms).

6. Continue moving to smaller and smaller time units, until consistency has been achieved at being able to accurately judge time increments of 3 to 5 ms.
