Song stuck in your head? Just hum to search

Do you know that song that goes, “da daaaa da da daaaa na naa
naa ooohh yeah”? Or the one that starts with the guitar chords
going, “da na na naa”? We all know how frustrating it is when
you can’t remember the name of a song or any of the words but the
tune is stuck in your head. Today at Search On,
we announced that Google can now help you figure it out—no
lyrics, artist name or perfect pitch required.�

Hum to search for your earworm

Starting today, you can hum, whistle or sing a melody to Google
to solve your earworm. On your mobile device, open the latest
version of the Google app or find your
Google Search widget
, tap the mic icon and say “what’s this
song?†or click the “Search a song†button. Then start
humming for 10-15 seconds. On Google Assistant, it’s just as
simple. Say “Hey Google, what’s this song?†and then hum the
tune. This feature is currently available in English on iOS, and in
more than 20 languages on Android. And we hope to expand this to
more languages in the future.

After you’re finished humming, our machine learning algorithm
helps identify potential song matches. And don’t worry, you
don’t need perfect pitch to use this feature. We’ll show you
the most likely options based on the tune. Then you can select the
best match and explore information on the song and artist, view any
accompanying music videos or listen to the song on your favorite
music app, find the lyrics, read analysis and even check out other
recordings of the song when available.

How machines learn melodies 

So how does it work? An easy way to explain it is that a
song’s melody is like its fingerprint: They each have their own
unique identity. We’ve built machine learning models that can match
your hum, whistle or singing to the right “fingerprint.â€

When you hum a melody into Search, our machine learning models
transform the audio into a number-based sequence representing the
song’s melody. Our models are trained to identify songs based on
a variety of sources, including humans singing, whistling or
humming, as well as studio recordings. The algorithms also take
away all the other details, like accompanying instruments and the
voice’s timbre and tone. What we’re left with is the song’s
number-based sequence, or the fingerprint.

We compare these sequences to thousands of songs from around the
world and identify potential  matches in real time. For example, if
you listen to Tones and I’s “Dance Monkey,†you’ll
recognize the song whether it was sung, whistled, or hummed.
Similarly, our machine learning models recognize the melody of the
studio-recorded version of the song, which we can use to match it
with a person’s hummed audio. 

This builds on the work of our AI Research team’s
music recognition technology
. We launched Now Playing on the
Pixel 2 in 2017, using deep neural networks to bring low-power
recognition of music to mobile devices. In 2018, we brought the
same technology to the SoundSearch feature in the Google app and
expanded the reach to a catalog of millions of songs. This new
experience takes it a step further, because now we can recognize
songs without the lyrics or original song. All we need is a
hum.

Hum to Search technology

So next time you can’t remember the name of some catchy song
you heard on the radio or that classic jam your parents love, just
start humming. You’ll have your answer in record time.
