Essay: One of the changes to the pop charts in the last 60 years is the demise of key changes

New Tedium writer Chris Dalla Riva looked at what has caused the disappearance of key change in pop music: "As hip-hop grew in popularity, the use of computers in recording also exploded too. Whereas the guitar and piano lend themselves to certain keys, the computer is key-agnostic. If I record a song in the key of C major into digital recording software, like Logic or ProTools, and then decide I don’t like that key, I don’t have to play it again in that new key. I can just use my software to shift it into that different key. I’m no longer constrained by my instrument".
