Whether you’re a musician, producer, or music lover, you may have found yourself stuck trying to find the key to a specific song.
Thankfully, gone are the days when you had to tediously calculate the sharps and flats on a sheet of music to know what key a song was in!
With today’s cutting-edge technology, you can identify the key with the push of a button... or two! Fortunately for all of us music nerds out there, many trustworthy websites and plug-ins can detect any musical key.
And fortunately for you, we tested a bunch of them to determine which are the best. So, without further ado, here are the four best key finder websites and plug-ins available today!
What Are The Best Key Finder Websites?
The internet is filled with various musical key-finding tools and websites. However, it’s somewhat challenging to find one that’s accurate.
As a musician, sometimes, these things must be as precise as possible. This is why we’ve compiled a list of four handy tools that are the most helpful.
Our top four include:
- Audio Keychain
- Mixed In Key
Powered by the Spotify Web API, Tunebat music key finder software is a powerful, free database of over 70 million songs.
- Large database of song tempos and keys
- Vocal remover technology
- Great for professionals and beginners
TuneBat is an online key finder website that lets you detect the key and the BPM of most released songs. It has a database of over 40 million songs for you to choose from!
What’s great about this website is that it’s powered by Spotify’s Web API. This guarantees that all the songs you find on the website are original versions that have been uploaded by the artist and haven’t been sampled or altered in any way.
This makes it much easier for DJs or other musical artists to create their own remixes.
All you have to do is type the song title into the search field or upload an audio file, and voila! It tells you the key and BPM of the track. It also tells you the song’s vitality, catchiness, enthusiasm, and release date.

TuneBat not only finds the song’s key and BMP, but it also includes a couple of other features. Let’s take a look at some of them!
Refined Filter Search
One of Tunebat’s best features is the refined filter search.
You know how when you’re setting up a music app account, it asks you to choose a few songs to establish the algorithm and learn what you like and don’t like? TuneBat’s refined filter search pretty much does the same thing.
It lets you pick up to five songs and then will search for others that are similar to them. The best part is that you can listen to any song directly from the website without using any music streaming service.
TuneBat also has a voice removal tool, which allows you to remove the artist’s vocals from the song. Surprisingly, it allows you to take whatever else you don’t want out of the track!
For example, with their track separation service, you can edit out the drums, bass, guitar, and anything else.
- Easy to use
- Has plenty of features
- Too many ads
This website is great for everyone! Whether you’re a musician, a DJ, or simply looking for a song key, TuneBat will get the job done.
Easily find the key of a song by extracting it from an MP3 (mp3 to key) or any other audio file, thanks to our Online Song Key Finder. Drop your audio file(s) in the song analyzer and instantly get the key in which a song was composed.
- Library of 6 million songs
- Reverse song search
- Quick song key search
GetSongkey is a website that helps you identify a song’s key and suggests similar tracks. With a library of 6 million songs, GetSongkey is one of the largest key-finder websites in the world.
This website isn’t only useful for those who want to know the key of a song, but it’s also a great tool for people who want to make a playlist based on a certain key.
Speaking of playlists in the same key, GetSongkey’s reverse song search is ideal for that. It simply detects other songs with the same key you searched for.
Furthermore, it can recognize a song’s chord progression and change it into any key you want.
- Easy to use
- Offers helpful tools
- Songs can’t be filtered by key
All in all, GetSongkey is a great tool for performing a quick song key search. It’s also an excellent resource for emerging DJs, producers, and musicians.
Quickly find the Key and BPM to any of your songs online! Search our massive song key database for compatible tracks to produce the perfect mashup.
- Good for analyzing own compositions
Unlike the first two websites we mentioned, AudioKeychain requires you to upload your own audio file to identify your track’s key. This is somewhat of a double-edged weapon.
On one hand, finding the key to a famous song might be pretty challenging. On the other hand, it’s pretty handy if you’re only looking for the key to your own music. This is why AudioKeychain is more suited for people who make their own music.
If you’re concerned about uploading your work online, rest assured. AudioKeychain features two modes: public and private. In public mode, anyone may view and listen to your audio file. In private mode, only you have access to it.
To use their service, you have to create an account first. Then, drag and drop the audio files you want onto the platform. Finally, click the ‘upload tracks’ button, and you’re done!
- Easy to use
- Maximum file size is 15 MB
- Only Supports Mp3 and Wav files
If you have a lot of audio recordings on your computer and want to know what keys they are, AudioKeychain is a great tool for that. It’s also ideal for musicians who create their own music.
However, it’s not the best option for someone simply looking for a song key. It certainly works; however, there are much easier websites for that purpose.
4. Mixed In Key (Software)
Mixed In Key Studio Edition analyzes your samples and provides advanced key and notation data to help you blend the perfect sounds in harmony.
- Offers extra features
Designed for professional DJs and music producers, Mixed In Key is an advanced software that’s a little more on the pro side. If you’ve got a track on your desktop and want to know its key, drag and drop it into the platform.
The software will instantly give you the song’s key, BPM, and energy level. Mixed In Key can also determine your song’s key and other information while listening to it!
Their website provides various plugins and bundles that offer key detection, melodies, chord composition, and rhythm generation. Since it is intended for professional use, it’s not free like the other websites we previously listed.
- Offers a lot of features
- Not suitable for beginners
This is a great tool for professionals, such as DJs and music producers. It’s not recommended for beginners or someone who only wants to identify a song key. It definitely gets the job done, but it’s simply…overqualified!
Are Key Finder Websites Accurate?
The short answer is no, not always. Most, if not all, key-finding websites are accurate to within 70-95%. However, it still depends on the track selection.
Some songs are more likely to be accurate than others. For example, if relative keys share the same key signature, the key finder can better detect the key.
Are Key Finder Websites Free?
If all you want to do is find a song key, most key finder websites will offer that for free. However, if you want to use an additional service, such as voice elimination, you’ll have to pay a subscription fee.
