Stay — The Kid LAROI y Justin Bieber (2021)

Two minutes and twenty-one seconds without a breather: a rising synth riff, drums that never stop and a chorus to sing at the top of your lungs. Four chords, and you already know three of them.

Why it's in this book

This song comes in January, the month when you learn, with Anti-Hero, that the four-chord loop can start on any of its chords. Stay is the month's second song. Its chords in class are F, G, A minor and E minor: three come from the loop you already play, and the fourth, E minor, replaces C. What you learn here is energy: a fast tempo that forces you to strum cleanly, without missing a stroke, and a chorus you sing almost shouting, with the second voice an octave away. In the room with no instruments you work on the chorus and the kick-drum beat with your feet; in the ukulele room, the four chords at full speed; in the music room, the drums play a kick on every beat and the keyboard plays the chords short and detached.

Why this song

Watch the music video with the sound down. Two singers dance through a city where everyone is frozen. The cars do not move, the people do not move. Only the two of them move.

Now turn it up. The music does the opposite of the picture: it never stops. The song lasts 2:21, shorter than almost any other song in this book, and it does not have a single calm moment.

The question on this page is: what makes a song sound in a hurry? Here the answer has three parts: the tempo, the drums and a riff that climbs.

Historical context

The Kid LAROI is an Australian singer and rapper. When "Stay" came out he was 17. Justin Bieber, from Canada, already had more than ten years of career behind him: his first big hit, "Baby", is also in this book.

The song was born almost by accident. LAROI was at the house of the producer Blake Slatkin with two other musicians, Charlie Puth and Omer Fedi. Puth started playing a melody on a keyboard. LAROI liked it so much that he wanted to build a song on it. Then he thought Bieber's voice would fit, and they recorded it together.

This is a Roland Juno-60, a synthesizer from the 1980s. The riff in "Stay" was played on one like this, which belonged to Slatkin. A synthesizer is a keyboard that makes its sound electronically: it can imitate other instruments or invent new sounds.

It was number 1 in the United States and in more than twenty countries. In Australia it spent 17 weeks at number 1. In the UK it stopped at number 2, behind an Ed Sheeran song, "Bad Habits".

Musical characteristics

A riff that climbs. The song kicks off with a synth riff: a few quick notes going up, one after another. That riff never goes away. And in the chorus something curious happens: the melody the voices sing is the same one the keyboard was playing. The riff turns into the song.

Four chords, one new. Underneath, four chords repeat the whole time, in the verse and in the chorus. In class they are F, G, A minor and E minor. You already have F, G and A minor from the loop in Love Story or Anti-Hero. The new one is E minor, which takes the place of C. That is why it sounds similar to those songs, but darker: it ends on two minor chords.

Drums that push. The song runs at 170 beats per minute. That is very fast: if it is hard to follow, count only every other beat and you will feel 85, a steady walk. The classroom drummer plays a kick drum on every beat, without skipping one. That beat is called four-on-the-floor: four kick-drum hits per bar, like in dance music.

Voices that leap. Again and again, LAROI and Bieber make a big jump upwards. Down low they sing with their chest voice, the one you speak with. Up high they switch to their head voice, lighter, the one you feel buzzing in your head rather than your chest. That switch is what makes the song sound like a shout.

A warning for when you play. The record is in B♭ minor, with five flats. In class we move it down a semitone, to A minor, which has none: that is transposing. The chords become F, G, A minor and E minor, all easy on the ukulele.

Hard facts: B♭ minor on the record and A minor in class, 4/4, 170 beats per minute (you can feel it at 85), 2:21. The form: intro with the riff, then verses, pre-choruses and choruses that follow one another without a break; one of the verses is sung by Bieber.

Guided listening

Play the music video. In the intro, listen to the synth riff. Do the notes go up or down?

In the first verse, tap the beat with your foot. If it is too fast, tap only every other beat.

When the chorus arrives, compare the vocal melody with the riff from the start. Does it sound familiar?

Listen for the voice leaping upwards. Notice the moment it switches from chest voice to head voice.

When Bieber sings his verse, listen for whether the chords underneath change. Are they the same four?

Trivia and curiosities

  • LAROI kept the song for almost a year before releasing it. He even asked his fans to flood the record label boss with messages so that he would let it come out.
  • Charlie Puth, who played the melody on the keyboard, is famous for having perfect pitch: he can name any note just by hearing it.
  • The whole song leaked online a month before its release. Even so, it reached number 1 in the United States.
  • It lasts 2:21. Today many hit songs are under three minutes long: people listen on their phones, and a short song gets replayed more often.

Classroom activities

  • Four-on-the-floor with your feet. The whole class stamps on every beat, non-stop, while the song plays. Then add claps on 2 and 4 on top of the stamps.
  • Clean strumming. Ukulele: F, G, A minor and E minor, one chord per bar. First at half tempo, counting at 85. When it works with no mistakes, at full speed.
  • The chorus in octaves. High voices sing the chorus at their pitch; low voices sing the same melody an octave lower. It is the same song, at two heights.
  • From Anti-Hero to Stay. Play the Anti-Hero loop (F, C, G, A minor) and then the Stay loop (F, G, A minor, E minor). Which chords do they share? Which one sounds darker?
  • Create. Make up a four-note riff that climbs, in A minor, and play it on the keyboard over the four chords. Could it be sung as a chorus?
