The most basic and annoying chord pattern that makes everything sound like a stupid folk song. It’s like your root note is telling its buddy the fourth and then its best friend the fifth. It’s everywhere and it’s never going away.
My guitar teacher forced me to play I IV V until I screamed into my pillow.
This song has I IV V so much it feels like a math test.
I IV V is the reason I hate country music and my ears.
