Shape of You — Ed Sheeran (2017)

A song that starts with four marimba notes and does not let go of them for four minutes. The same four notes you can play on the classroom xylophone.

Why it's in this book

This is February's anchor song, the one you will spend most time on that month. It is in the book because of its riff: four marimba notes that repeat from start to finish and fit completely on an Orff xylophone. On top of that, the whole song uses the same four chords, which in class are A minor, D minor, F and G. It is a minor loop, a cousin of the major loop in Love Story or Perfect: it starts on a minor chord and sounds darker. Like Bad Guy, it shows that a riff can be the whole song. In the room with no instruments you work on the voice and on the tresillo rhythm with your body; in the ukulele room, the four chords; in the music room, the xylophones play the riff, the ukulele bass doubles it and the drums play a tropical beat.

Why this song

Listen to the first few seconds of the song. Before Ed Sheeran sings anything, you hear an instrument with wooden bars. It is a marimba, the big sister of the xylophone in your classroom.

A month after releasing it, Sheeran played it on American TV with classroom music instruments: the same kind many schools have. It worked just as well. That video is in Resources.

The question on this page is: can a whole song stand on four notes? Here the answer is yes, and you can check it on the xylophone.

Historical context

Ed Sheeran is an English singer and guitarist. He started out playing alone in pubs, with an acoustic guitar and a pedal that records loops: he plays something, the machine repeats it, and he plays on top. That way one person can sound like a whole band.

"Shape of You" came out on 6 January 2017, the same day as another of his songs, "Castle on the Hill". They were the first two songs from his third album, ÷ (the division sign). "Perfect", which is also in this book, is from the same album.

The song was not meant to be his. He started writing it with two songwriters, Steve Mac and Johnny McDaid, with other artists in mind, such as Rihanna. Steve Mac played the first notes on the keyboard and Sheeran started tapping on his guitar as if it were a drum. Halfway through the session they decided to keep it.

These are Orff xylophones, like the ones in the music room: wooden bars played with mallets. The riff in "Shape of You" is played on a marimba, which is a bigger, deeper xylophone. The notes are played the same way.

It was number 1 in 34 countries. In December 2018 it became the first song in history to reach 2 billion plays on Spotify. In Spain it has gone platinum eleven times.

Musical characteristics

A riff that never stops. A riff is a short phrase that repeats over and over. The one in this song is played on a marimba and uses only four different notes. When a figure repeats like this through a whole song, it is also called an ostinato, Italian for "stubborn". Listen to it: it never goes away.

Four chords, the whole song. Under the riff there are four chords. They are always the same and always in the same order: in the verse, in the chorus and at the end. In class they are A minor, D minor, F and G. The first two are minor, which is why the song sounds a little dark even though you can dance to it. This repeated set of chords is a chord progression.

The rhythm that limps. Clap along and listen to the rhythm of the marimba and the percussion. It does not move in equal hits. It goes in groups of three, three and two: "ONE-two-three, ONE-two-three, ONE-two". That rhythm is called the tresillo. It comes from African and Caribbean music, and it is the base of styles like reggaeton and dancehall.

A piece of another song. One line in the pre-chorus recalls "No Scrubs", a 1999 hit by the group TLC. Using a piece of another song's melody by singing it again is called interpolation. That is why its writers are also credited as writers of "Shape of You".

A warning for when you play. The record is in C♯ minor, a key with four sharps. In class we play it in A minor, which has none. We move everything down four semitones: that is transposing. That way the riff fits on the xylophone bars without any sharps or flats.

Hard facts: C♯ minor on the record and A minor in class, 4/4, 96 beats per minute, 3:54. The form: intro, verse, pre-chorus, chorus, verse, pre-chorus, chorus, bridge and final chorus.

Guided listening

Play the music video. In the intro, listen only to the marimba. Count how many times it repeats the same phrase before the voice comes in.

When the first verse starts, try to keep hearing the marimba under the voice. Is it still there?

In the chorus, clap the "three, three and two" rhythm. If it fits, you have found the tresillo.

Listen to the "oh I, oh I" chorus. Everyone sings the same note at the same time: that is singing in unison.

At the end, listen for whether the chords have changed at any point. Compare the last chorus with the first: what is new?

Trivia and curiosities

  • In 2022 Sheeran went to court because two other musicians said he had copied a phrase from their song "Oh Why". The judge ruled in his favour. Sheeran said there are very few chords in pop and only twelve notes, so coincidences are bound to happen. It is the same idea as this book: lots of songs share chords.
  • In the music video, Sheeran trains as a boxer and fights a real sumo wrestler, Yamamotoyama. It is a tribute to the Rocky films.
  • He first wrote it with Rihanna in mind. He changed his mind when he heard himself singing a line about putting Van Morrison on the jukebox: "she's not really going to sing that, is she?"
  • For years it was the most-played song on Spotify. Today only "Blinding Lights" by The Weeknd beats it.

Classroom activities

  • The riff on xylophone. Work out the riff by ear on the xylophone, in A minor. It uses four notes from the A minor scale, all on the natural bars. When you have it, play it non-stop while another group sings.
  • Body tresillo. The whole class claps "three, three and two", counting out loud "ONE-two-three, ONE-two-three, ONE-two". Then feet keep the beat while hands play the tresillo, at the same time.
  • Play the four chords. Ukulele: A minor, D minor, F and G, one chord per bar. Since they never change, you can play the whole song with those four.
  • The band. Xylophones on the riff, ukulele bass doubling the riff an octave lower, drums with the tropical beat. Everyone else sings the "oh I, oh I" chorus in unison.
  • Create. Make up your own four-note riff in A minor and play it over the same four chords. Can it hold up a whole song?
