Ideal Prediction Program

In an ideal world, exposure to music would lead listeners to form the following prediction programs:

1. Pitch Proximity.
   Expect an ensuing pitch to be near the current pitch.
   
   
2. Regression-to-the-mean.
   As the melody moves further away from the center of the pitch distribution, expect the next pitch to move closer to the mean.
   
   
3. Downward Steps.
   Since most intervals are small, and since most leaps ascending, then expect a descending small interval.
