Use the estimated key to plan a compatible vocal range, harmony, or remix idea.
Practice and cover planning
Set a metronome, rehearse at the right pace, and prepare a key that suits your performance.
BPM
Estimated beats per minute—the overall speed of the track.
Musical key
The estimated tonal center and major or minor scale.
Key confidence
Confidence only for the key estimate—not BPM or overall accuracy.

Frequently asked questions
Do I need permission to analyze a YouTube video?
Yes. Only import and analyze content you own or have permission to process. A YouTube link does not grant rights to the recording.
How accurate are the BPM and key results?
They are estimates. Clean recordings with a steady tempo and clear tonal center are usually easier to analyze than dense, live, heavily edited, or changing arrangements.
Can MeloLab analyze every YouTube link?
No. Private, age-restricted, region-restricted, live, or unavailable videos may not be accessible.
What does key confidence mean?
It is the analyzer’s confidence in the estimated musical key, not a guarantee and not a confidence score for BPM.
What if the song changes tempo or key?
The page analyzes the full imported track and returns one overall estimate. Songs with changes may need closer listening or section-by-section analysis elsewhere.
Does the analysis cost credits?
Importing the permitted source and running BPM/key analysis do not charge generation credits, but sign-in is required for the YouTube import.
