Dr. Derek conducts an experiment where he presents two sequences of notes simultaneously through earphones, one to the right ear and one to the left. The notes presented to each ear jump up and down, meaning that they do not create a scale. However, the results indicate that the listeners perceived smooth sequences of notes in each ear, with the higher notes in the right ear and the lower ones in the left ear. What effect is Dr. Derek researching

Scale illusion

Explanation:

Scale illusion is the combination of two unconnected notes into a single Melody,the notes being combined are planned do not create a scale but yet they come beautiful when played into both ears of the listener.

Dr Derek experiment proves that although the combined notes didn't produce a scale doesn't mean they can't produce beautiful melodic sounds.

those sounds of the natural world are bioacoustics, and they're more than a false-color spectrogram of data from the musiamunat conservation area.
