The effect of overtones in the brain seems to be of great interest. That’s why I would like to introduce the corresponding hearing test here. Dr. Schneider, the head of the study, provides on his website a hearing test developed by him, with which I have been testing my Masterclass students for years in order to develop an individual and optimal learning strategy for everyone.
This short test plays a series of tone pairs in which you are asked to decide spontaneously whether the second sound feels higher or lower than the first. At the end you get an evaluation of the degree to which you are fundamental or overtone listener, i. e. whether your hearing processes the sound more in the left brain half (fundamental listener) or more in the right brain half (overtone listener). If you are interested in the background of the work of the Heidelberg researchers, you can download the specialist article here.

Leave your result in the comments. I’m curious how overtone singers cut off. My result is: extreme overtone listener.
