Our natural ability to hear and perceive the nuances of music is incomparably far from our understanding of them - although there are exceptions. To test this, the Harvard University Music Laboratory developed a series of unusual topical tests.
These tests are characterized by creativity in asking questions, and they are needed, first of all, to collect data for a large study of how the human brain perceives music. To take part, you need to follow the link, stock up on good headphones and try to avoid noise sources nearby. The test is best done on a laptop or desktop computer. It is also important to honestly indicate your gender and age, the accuracy of the assessment depends on this.
The first test is devoted to tonal deafness - participants are asked to listen to a sequence of tones, setting marks which sounds lower and which sounds higher. This is a surprisingly difficult task, although it can be completed in 5 minutes.
The second part consists of international tests, in one of which, by the sound of an unknown folk song, you need to guess what it is intended for: a celebration, lullaby, drinking, dance melody, etc. In another, participants are asked to listen to an unfamiliar arrangement of an unknown melody and guess if it is aimed at an adult audience or children and adolescents. The third test is a critical assessment of a computer-synthesized copy of a certain melody. The user needs to evaluate how similar it is to the original. All responses are collected anonymously and stored only on the Harvard University server.
