Let the beat drop / Suelta el beat

Today’s “I have too much time on my hands during my funemployment” presentation analyzes the impact of musical rhythm changes on your brain. My idea for this topic came from listening to the song “Ausencia” by Willie Colón and featuring Héctor Lavoe. The first time I heard this song was only a few months ago, and no exaggeration, I was genuinely floored the first time I heard it. The song begins slow and sad; a man quietly telling of his woman leaving him and the fallout from that break. At the 1:38 mark, horns start playing, marking a swelling in the song. Then, at the 1:50 mark, the song shifts abruptly from mournful bolero to an aggressive salsa beat. Hector is now basically yelling into the void that he needs his woman back and he will keep waiting for her or else he will go loco. Not to get too graphic here, but I give this beat transition the award for Most Erotic Transition in a Song that I’ve Heard.

That got me to thinking about the musical genius that first thought of abruptly switching rhythms in songs, what other songs have this switch, and why it hits so good when you hear it. I hopped online, opened 45 tabs, loaded them onto Gemini Notebook, and here we have another presentation. TLDR; your brain is wired to recognize patterns, your brain falls into a pattern at the beginning of Ausencia, and then is shocked and awed (and maybe aroused?) by the rhythm switch in the middle, and responds by releasing a ton of dopamine, a “feel good hormone” =). I find this neurological effect really interesting and impressive. The last slide in this presentation sums it all up in a way only an AI generated resource can: “A beat switch is a masterful manipulation of human biology.”
