This experiment is looking at how many instruments people can count when they are playing together—for example, if listening to a recording of a string quartet, how well can people tell if it is 1, 2, 3, or 4 instruments playing at any given moment, and how readily can they identify when the number changes (one or more start or stop). My musical examples go up to 5 instruments (or musical “voices”). The hypothesis is that trained musicians would be able to identify 1-3 quite well, and then that accuracy and ability to identify changes would go down fairly rapidly with textures of more than 3 voices, and that people without musical training would perform less well than those with musical training.
