Earth, Wind & Fire's iconic 'September' chorus, 'ba-dee-ya', has long been a subject of intrigue for fans. The new documentary, 'Earth, Wind And Fire (To Be Celestial vs The Weight Of The World)', offers a fascinating insight into the origins of this enigmatic phrase. While some band members, like Ralph Johnson, claim it means 'whatever you want it to be', the truth is far more nuanced. In my opinion, the 'ba-dee-ya' is a Brazilian scat, a playful and rhythmic vocal technique that was a staple of the band's live performances. This is supported by Philip Bailey, who reveals that Maurice White and he often listened to Sérgio Mendes' band Brasil '66, and would scat over the melodies. What makes this particularly fascinating is the way it showcases the band's creativity and their ability to blend different musical styles. The 'ba-dee-ya' is not just a random phrase, but a deliberate choice that adds to the song's energy and catchiness. From my perspective, it's a testament to the band's musical prowess and their willingness to experiment. This raises a deeper question: how many other musical phrases or sounds have we taken for granted, without considering their origins or meanings? The documentary also sheds light on the personal lives of the band members, including the birth of Maurice White's son, Kabhran, and the impact it had on the creation of the song. This adds a layer of emotional depth to the music, making it more than just a catchy tune. In conclusion, 'ba-dee-ya' is more than just a chorus; it's a musical signature that embodies the spirit of Earth, Wind & Fire. It's a reminder that music is not just about the notes and lyrics, but also about the emotions and stories that lie behind them. So, the next time you hear 'ba-dee-ya', take a moment to appreciate the rich history and meaning behind it. It's a small detail that makes a big difference.
