2026 translation
A fixed idea that takes over and leaves room for nothing else. In 1921 it was a berretín; today it is a hyperfixation.
Every verse is cross-checked in at least two sources: the published lyrics and the record of Gardel's recording. The tango for each word plays on Spotify. Before publishing, the Foundation confirms the transcriptions.
