Ariana Grande dropped her new single "Imagine," and Twitter is obsessed with this one specific part

Ariana Grande dropped the new single "Imagine" last night, and fans on Twitter are losing it over those whistle notes at the end of the song.

Ariana Grande dropped the new single “Imagine” last night, and oh boy, members of the Grande fandom did not know they were in for such a treat. Fans have already started to speculate that “Imagine” is about Mac Miller (the evidence: he has an “Imagine” tattoo and her lyric about ordering pad thai is somewhat similar to his lyric about a girl who loves stir fry), but this is all speculation. But something we don’t have to speculate about is whether or not Grande hit those whistle notes at the end of the song, because hell yes she did.

The whistle register is the highest register in the human voice and only a handful of singers—including Mariah Carey and Whitney Houston, most famously—can do it. Grande is one of them. Though we’ve heard Grande get into her whistle register before—like when she covered Carey’s “Emotions”—that didn’t make listening to “Imagine” any less mind-blowing.

Check out the full lyrics to Ariana Grande’s “Imagine,” below:

Step up the two of us, nobody knows us
Get in the car like, “Skrrt”
Staying up all night, order me pad thai
Then we gon’ sleep ’til noon
Me with no makeup, you in the bathtub
Bubbles and bubbly, ooh
This is a pleasure, feel like we never act this regular

Click, click, click and post
Drip-drip-dripped in gold
Quick, quick, quick, let’s go
Kiss me and take off your clothes

Imagine a world like that
Imagine a world like that
We go like up ’til I’m ‘sleep on your chest
Love how my face fits so good in your neck
Why can’t you imagine a world like that?
Imagine a world

Knew you were perfect after the first kiss
Took a deep breath like, “Ooh”
Feels like forever, baby, I never thought that it would be you
Tell me your secrets, all of the creep shit
That’s how I know it’s true
Baby, direct it, name in the credits
Like the movies do

Click, click, click and post
Drip-drip-dripped in gold
Quick, quick, quick, let’s go
Kiss me and take off your clothes

Imagine a world like that
Imagine a world like that
We go like up ’til I’m ‘sleep on your chest
Love how my face fits so good in your neck
Why can’t you imagine a world like that?
Imagine a world

Can you imagine it?
Can you imagine it?
Can you imagine it?
Can you imagine it?
Can you imagine it? (Can you imagine?)
Can you imagine it? (Can you imagine?)
Can you imagine it? (Ooh)
Imagine that
Imagine it, imagine it
Imagine it, imagine it
Imagine, imagine
Imagine, imagine
Imagine, imagine

…and then listen to the song, here (the whistling starts at the 2:44 mark).

We’ll be whistling to this song all day.
