Three songs from different genres that were scientifically the same enough to experiment between musicians/non-musicians with:
“Three musical pieces were used in the experiment:
(a) Stream of Consciousness by Dream Theater;
(b) Adios Nonino by Astor Piazzolla; and
(c) Rite of Spring (comprising the first three episodes from Part I: Introduction, Augurs of Spring, and Ritual of Abduction) by Igor Stravinsky.
These are a progressive rock/metal piece, an Argentinian New Tango, and an iconic 20th century classical work, respectively, thus covering distinct musical genres and styles. All three selected pieces are instrumental and have a duration of about 8 min. These pieces of music were chosen based on the following criteria: to have an appropriate duration for the experimental setting used; to belong to different genres in order allow generalization of the obtained findings; to contain a high amount of acoustic variation and that the amount be comparable between the three pieces (the mean normalized standard deviation across all 25 extracted musical features [Alluri et al., 2012] differed less than 10% between the stimuli); to have a comparable musical structure (starting with a session of solo instrument and then introducing the larger ensemble after few minutes); and lastly to not contain lyrics to avoid the confounding effects of semantics.”
