The corneta was used by the PDT during its 2021 pre-campaign activity ahead of Ciro Gomes's run for president of Brazil in 2022, when the party's number 12 and its campaign sound became familiar at rallies and online. Short clips from those events circulated on soundboards and social media, where supporters reused the horn to signal PDT support, mock rivals and add election flavour to edits. It remains a recognisable shorthand for that campaign, especially among Brazilian users who followed the 2022 race.
