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.
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.
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.
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".
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.
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?

Esta canción llega en enero, el mes en el que aprendes, con Anti-Hero, que el bucle de cuatro acordes puede empezar por cualquiera de ellos. Stay es la segunda canción de ese mes. Sus acordes en clase son fa, sol, la menor y mi menor: tres son del bucle que ya tocas, y el cuarto, mi menor, sustituye al do. Lo que aprendes aquí es energía: un tempo rápido que te obliga a rasguear limpio, sin que se te escape ningún golpe, y un estribillo que se canta casi gritando, con la segunda voz a una octava. En el aula sin nada se trabaja el estribillo y el pulso de bombo con los pies; en el aula con ukelele, los cuatro acordes a toda velocidad; en el aula de música, la batería toca un golpe de bombo en cada pulso y el teclado toca los acordes cortos y picados.
Mira el videoclip con el volumen bajado. Dos cantantes bailan por una ciudad en la que todo el mundo se ha quedado congelado. Los coches no se mueven, la gente no se mueve. Solo se mueven ellos dos.
Ahora súbelo. La música hace lo contrario que la imagen: no se para nunca. La canción dura 2:21, menos que casi cualquier canción de este libro, y no tiene ni un momento de calma.
La pregunta de esta página es: ¿qué hace que una canción suene con prisa? Aquí la respuesta tiene tres piezas: el tempo, la batería y un riff que sube.
The Kid LAROI es un cantante y rapero australiano. Cuando salió «Stay» tenía 17 años. Justin Bieber, canadiense, ya llevaba más de diez años de carrera: su primer gran éxito, «Baby», también está en este libro.
La canción nació casi por casualidad. LAROI estaba en casa del productor Blake Slatkin con otros dos músicos, Charlie Puth y Omer Fedi. Puth se puso a tocar una melodía en un teclado. A LAROI le gustó tanto que quiso construir una canción encima. Después pensó que la voz de Bieber encajaría, y la grabaron juntos.

Este es un Roland Juno-60, un sintetizador de los años ochenta. El riff de «Stay» se tocó en uno como este, que era de Slatkin. Un sintetizador es un teclado que fabrica el sonido con electrónica: puede imitar otros instrumentos o inventar sonidos nuevos.
Fue número 1 en Estados Unidos y en más de veinte países. En Australia pasó 17 semanas en el número 1. En el Reino Unido se quedó en el número 2, por detrás de una canción de Ed Sheeran, «Bad Habits».
Un riff que sube. La canción arranca con un riff de sintetizador: unas pocas notas que suben, rápidas, una detrás de otra. Ese riff no se va nunca. Y en el estribillo pasa algo curioso: la melodía que cantan las voces es la misma que tocaba el teclado. El riff se convierte en canción.
Cuatro acordes, uno nuevo. Debajo, cuatro acordes que se repiten todo el rato, en verso y en estribillo. En clase son fa, sol, la menor y mi menor. Fa, sol y la menor ya los tienes del bucle de Love Story o Anti-Hero. El nuevo es mi menor, que ocupa el sitio del do. Por eso suena parecida a esas canciones, pero más oscura: termina en dos acordes menores.
Una batería que empuja. La canción va a 170 pulsos por minuto. Es muy rápido: si te cuesta seguirlo, cuenta solo uno de cada dos y sentirás 85, un paso tranquilo. La batería del aula toca un golpe de bombo en cada pulso, sin saltarse ninguno. Ese ritmo se llama four-on-the-floor, «cuatro en el suelo»: cuatro golpes de bombo por compás, como en la música de baile.
Voces que saltan. Una y otra vez, LAROI y Bieber dan un salto grande hacia arriba. Abajo cantan con la voz de pecho, la de hablar. Arriba pasan a la voz de cabeza, más ligera, la que se nota vibrar en la cabeza y no en el pecho. Ese cambio es lo que hace que la canción suene a grito.
Un aviso para cuando toques. El disco está en Si♭ menor, con cinco bemoles. En clase lo bajamos un semitono, a La menor, que no tiene ninguno: eso es transportar. Los acordes quedan fa, sol, la menor y mi menor, todos fáciles en ukelele.
Datos duros: Si♭ menor en el disco y La menor en clase, 4/4, 170 pulsos por minuto (se puede sentir a 85), 2:21. La forma: intro con el riff y, después, versos, preestribillos y estribillos que se alternan sin pausa; uno de los versos lo canta Bieber.
Pon el videoclip. En la intro, escucha el riff del sintetizador. ¿Las notas suben o bajan?
En el primer verso, marca el pulso con el pie. Si es demasiado rápido, marca solo uno de cada dos.
Cuando llega el estribillo, compara la melodía de la voz con el riff del principio. ¿Te suena?
Escucha los saltos de la voz hacia arriba. Fíjate en el momento en que pasa de la voz de pecho a la voz de cabeza.
Cuando canta Bieber su verso, escucha si los acordes de debajo cambian. ¿Son los mismos cuatro?
