Self-study
A recent study of perfect pitch—the ability to identify the pitch of an isolated musical note—found that Support a high percentage of people who have perfect pitch are related to someone else who has it. █████ █████ ███████ ███████ ██████ ███ ██████████ ███ ████ ██████ ████ █████ ████ ██████ ███████ █████ ██ █ ███████████ ██ ███████ ████████
Summarize Argument: Phenomenon-Hypothesis
The author concludes that perfect pitch is a result of genetics. She supports this hypothesis by pointing to a correlation: those with perfect pitch tend to also have relatives with perfect pitch.
Notable Assumptions
The author assumes that perfect pitch is something that can be inherited genetically. She also assumes that there are no alternative hypotheses to explain the observed correlation—that is, she assumes that there are no other, non-genetic factors that could lead to sets of relatives all sharing perfect pitch.
