Today any song that becomes popular on the radio is promised to get a bunch of covers made by hundreds of people on YouTube. I didn’t know what song to talk about in this blog so I did some research and discovered that the song “Yesterday” by The Beatles is the most covered in history. In the past oral songs were typically the ones to be covered by different people in attempts to keep it flowing through family trees. Today we can listen to music repeatedly whenever and wherever we want, this has changed the way we listen to music. With this new technology, it’s hard to change a song completely since there are written or recorded versions of the song lyrics, so the game of broken telephone doesn’t become a problem here. “Yesterday” was recorded in 1965, the song is about a man being heartbroken over a breakup with his girlfriend. They keep referring to yesterday as the day that the breakup occurred and how they wished they knew it was coming, cause yesterday they were so in love before they got the news. The way The Beatles recorded the song it’s clear it has a sad tone making it have a slow tempo. The violin and acoustic guitar are heard throughout the whole song and create harmony when the lyrics are sung over them while keeping the tone the same the entire time. When Katy Perry covers this song at a tribute to The Beatles in 2014, she changes the word man to women (time 0:33) so the song can be sung from her perspective. There isn’t a problem with this because it doesn’t change the message or emotions expressed through the lyrics that tell a story about a breakup. There’s a moment when Katy Perry changes the tone of the song when she adds a high note in minute 2:09 which for a moment changes the song’s harmony.
