The basics
What is TuneBat?
TuneBat is a free, browser-based music database and audio-analysis tool. It answers one question extremely well: what is actually going on inside this track, musically and numerically? Search any title and you get a compact readout — the key in standard notation, the same key translated into Camelot notation, the tempo in beats per minute, and a set of scores describing the character of the record.
Every recording has properties you cannot read off the cover. It sits in a key. It moves at a tempo. It carries a certain weight and brightness. Musicians have always worked these out by ear, which is a skill worth having and a slow way to get through a crate of two hundred records before a Friday night.
You can run that lookup from this page. The search box above is wired straight into the catalog, so typing a song title takes you directly to its key, tempo and Camelot code. Nothing to install, no account required for a basic lookup, and no music theory needed beyond what this page explains.

Three ways in
Three ways to use TuneBat
Look a track up by name, analyze a file you already have, or go hunting by the qualities you want.
The TuneBat key & BPM analyzer
Upload an audio file of up to roughly 75 MB and it reports the key, Camelot key and tempo in seconds. This is the one for demos, edits and anything unreleased.
TuneBat advanced search
Search by qualities rather than by name. Filter on key, BPM range, energy, danceability, happiness and popularity, and seed it with tracks you already like.
The data
What every TuneBat metric means
Two of these describe the music theory — the musical key and the tempo. The rest describe the feel, each on a simple scale so tracks can be compared side by side.
Key
A–GThe tonal home of the track — the note its melody and chords resolve to. Shown in standard notation, like F# minor or C major.
Camelot
1A–12BThe same key rewritten as a number plus a letter, so you can spot compatible tracks instantly without thinking in sharps and flats.
BPM
tempoBeats per minute — the speed of the pulse you tap your foot to, and the number you match when beatmixing two records.
Energy
0–100How intense and active the track feels. Loud, fast, densely arranged music scores high; sparse ballads score low.
Danceability
0–100How suited the track is to dancing, drawn from its tempo, how steady the rhythm is, and how hard the beat lands.
Happiness
0–100Musical positivity, sometimes called valence. High scores sound bright or euphoric; low scores sound sombre or tense.
Loudness
dBAverage loudness across the whole track — a quick read on how heavily it was compressed and mastered.
Popularity
0–100How much attention the track is getting right now, relative to everything else in the catalog.
Harmonic mixing
The Camelot wheel, explained
Camelot notation exists to spare you from doing key theory in a dark room at one in the morning.
Every key gets a code: a number from 1 to 12, and a letter. A means minor, B means major. The numbers sit around a wheel so that neighbours are close musical relatives rather than arbitrary steps.
Once a track is labelled, three moves are reliably safe:
- Same code. Identical key. Always works.
- Same number, swap the letter. 8A to 8B — relative minor and major, sharing every note. A change of mood without a change of colour.
- One step around, same letter. 8A to 7A or 9A. A small, smooth lift or drop in tension.
Jumping to a code that is neither adjacent nor a letter swap is where clashes come from — not a rule against it, just a reason to know you are doing it. For the wider theory behind this, see harmonic mixing.
Who uses it
Who uses TuneBat, and why
The same readout answers quite different questions depending on who is asking.
DJs
Harmonic mixing lives or dies on key. Knowing the incoming track sits one step around the Camelot wheel from the one already playing is the difference between a transition that lifts the room and one that clashes.
Producers
Pitching a sample to fit your session, choosing what key to build a remix in, or hunting for a reference track at your working tempo — all of it starts with knowing the numbers.
Singers and bands
Checking whether a song sits inside your range before rehearsal, and working out how many semitones to transpose it if it does not.
Dance and fitness instructors
Building a class playlist around a target tempo, so the warm-up, the working set and the cool-down each land in the right BPM band.
Students and the curious
Checking your ear against an algorithm after working a key out yourself, or just satisfying the itch to know what makes a track tick.
Step by step
How to find a song's key with TuneBat
Four steps from a song title to an answer you can act on.
- 1
Search the title
Type the song, the artist, or both if the title is a common one. Pick the right release from the results — versions and remasters can genuinely differ in tempo.
- 2
Read the key and tempo
Take the standard key if you are transposing or playing along, and the Camelot code if you are planning a mix. The BPM is your beatmatching target.
- 3
Check it against your ear
Play the track and count the pulse. If the tempo feels like half or double what is listed, trust the count — that is the most common disagreement. Our disclaimer covers why readings drift.
- 4
Go wider from there
Use the advanced search to find more tracks in the same key and tempo band, and the analyzer for anything the catalog does not cover.
FAQ
TuneBat questions, answered
What is TuneBat?
TuneBat is a browser-based music database and audio-analysis tool. It reports the musical key, tempo in BPM and Camelot code of a song, along with scores for energy, danceability, happiness, loudness and popularity. The catalog covers more than 70 million tracks, and you can search it from the box at the top of this page.
Is TuneBat free to use?
Yes. Looking up a song and reading its key, BPM and audio metrics works straight from the browser, with nothing to install and no account needed for basic lookups.
How accurate are TuneBat key and BPM readings?
They are algorithmic estimates, and for steady four-to-the-floor pop, dance and hip-hop they are dependable. Two failure modes are worth knowing. Tempo is sometimes reported at half or double what you would count, and key detection can land on the relative major or minor instead of the true one — those two keys share the same notes, so they are genuinely easy to confuse. Treat the reading as a strong first guess and let your ears settle any argument.
How do I find the key of a song?
Type the song title, the artist, or both into the search box on this page and you will be taken to its entry, where the key appears in both standard and Camelot notation alongside the tempo. If the track is unreleased or missing from the catalog, upload the audio file to the analyzer instead and it will work the key out from the sound itself.
What does a Camelot code like 8A mean?
The number is a position on a twelve-point wheel and the letter is the mode: A for minor, B for major. So 8A is A minor. Anything sharing that number, or sitting one number either side with the same letter, will generally mix without clashing.
Can I search by tempo or mood instead of by name?
Yes. The advanced search filters the catalog by key, BPM range, energy, danceability, happiness, loudness and popularity, and you can seed it with up to five tracks you already like to surface similar records.
Other options
Looking for a TuneBat alternative?
TuneBat is not the only way to get a key and tempo, and it is not the best fit for every job. Web databases, file analysers and the DJ software you already own each answer a different question.
