Bad Guy — Billie Eilish (2019)

An almost empty song: a bass line, some finger snaps and a whispering voice. With that little, Billie Eilish and her brother reached number 1 in the United States.

Why it's in this book

"Bad Guy" is the March song, and it comes together with "Bella ciao". Both use the same three chords, A minor, D minor and E7, even though one belongs to the 20th century and the other to the 21st. That shows that a progression is a place many songs can visit, not a song. Here the bass is the song: a three-note riff played by the ukebass and the xylophone. In your classroom with no instruments, you sing the half-spoken verse, which leaves nobody out, and the choir says "duh". With ukuleles you play Am–Dm–E7. In the music room, the ukebass plays the riff, the drums stay dry and the keyboard does the "duh". At the end of the term you record it.

Why this song

If you have played Plants vs. Zombies, this song may ring a bell. Billie Eilish has said the music from that video game was one of her starting points. The other was the theme song of a Disney series, "Wizards of Waverly Place".

That is where the cartoon feel of the synth riff comes from. The song is a little scary and a little funny at the same time.

The question on this page is: how many instruments does it take to reach number 1? The answer: very few.

Historical context

Billie Eilish was born in Los Angeles in 2001. She records her songs with her older brother, Finneas O'Connell, who produces them. They started at home, without a big studio.

"Bad Guy" came out on 29 March 2019, the same day as her first full album. Billie was 17. The two siblings wrote it together.

This is how it sounded live in 2019, at the Coachella festival: three people on a huge stage. Billie sings, Finneas plays keyboard and there is a drummer at the back. Nothing else is needed.

The song reached number 1 in the United States. In doing so it ended a record run: "Old Town Road", by Lil Nas X, had been at the top for 19 weeks in a row. In 2020 it won the two biggest Grammys a song can win.

Musical characteristics

Almost nothing. Listen to the start: a bass, a kick drum and some finger snaps. That is all. The snaps are recorded very close and very loud, so they sound like a drum hit. When only a few instruments play, each one is very clear.

The bass is in charge. In most songs the bass stays underneath, holding things up. Here it is at the front. It plays a short pattern of notes that repeats again and again. That is called a riff: a short phrase that repeats and that you recognise at once.

A voice that almost speaks. Billie does not shout or hold long notes. She whispers, as if telling you a secret. In the chorus she almost talks. That is why anyone can sing this song: you do not need to reach difficult notes.

Three slightly scary chords. The song turns around three chords. The first two are minor and sound dark. The third changes one note, and that note pulls hard back to the first chord, like a magnet. That third chord is called the dominant: it wants to go home. This series is called a chord progression, and its name is i–iv–V7.

The "duh". After the chorus, Billie says "duh". Right after it, the cartoon-like synth riff comes in. That is the moment everybody remembers.

A second song inside. Near the end, everything changes. The beat slows down and the sound becomes darker and lower. It is as if another song had started. A change like this is a tempo change.

A warning for when you play. The record is in G minor: Gm–Cm–D7. In class you play it in A minor, Am–Dm–E7, one tone higher, because those chords are much easier on the ukulele. Moving a whole song to another pitch is called transposing.

Hard facts: G minor on the record and A minor in class, 4/4, 135 beats per minute in the first part and slower in the second, 3:14. The form: a fast song with verse, chorus and the "duh", then a slow final section.

Guided listening

Play the music video. At the start, count how many different sounds you hear. Do you get to five?

When she starts singing, focus on the bass. Hum it. That is the riff you will play on ukebass and xylophone.

When the "duh" arrives, listen to what comes right after it. It is another riff, this time on synth. Compare it with the bass riff: which one is higher?

Now wait for the final section. Tap the beat with your hand before and after the change. Does your hand go faster or slower?

Trivia and curiosities

  • One of the sounds in the song is not an instrument: the beeping of a pedestrian crossing in Sydney. Billie recorded it on her phone in 2017. Any sound can end up in a song.
  • There is a version with Justin Bieber, from July 2019. The chords are the same; only the singers change.
  • Billie wrote the song at 16 or 17, and her brother produced it. The whole album was a family job.
  • "Bad Guy" and "Bella ciao", which many of you know from the series "Money Heist", share the three chords. Try it: play Am–Dm–E7 and sing one song and then the other on top.

Classroom activities

  • Snaps and voice. No instruments: half the class snaps on beats 2 and 4, the other half says the half-spoken verse. Then everyone says "duh" together.
  • The riff. Ukebass and xylophone: learn the bass riff and repeat it non-stop while the others listen. When it works, someone says the verse on top.
  • The three chords. Ukulele: Am, Dm, E7, one chord per bar. Notice E7: what does it ask you to do next?
  • Two songs, one place. Play Am–Dm–E7 and sing a bit of "Bad Guy" and then a bit of "Bella ciao". Do both fit? Answer yes or no.
  • Record it. In the music room, with the band: ukebass on the riff, dry drums, keyboard on the "duh". Record it and listen back next lesson.
