What key is this song in? Click while a tab plays music to detect its musical key and BPM — 100% on-device, nothing uploaded. What key is this song in? Now you can find out in one click — while the song is still playing. Song Key & BPM Finder listens to the tab you're already playing music in and tells you its musical key and tempo. No file to upload, no track name to type — just click. How it works (3 steps): Play a song in any tab — YouTube, Spotify Web, SoundCloud, Bandcamp, anywhere audio plays. Click the extension icon and press "Detect key & BPM". It captures about 20 seconds of the tab's audio and analyzes it right on your device. What you get: • The key — e.g. "A minor" • The relative key (the major/minor that shares the same notes) • The BPM (tempo) • A confidence rating so you know how sure the result is • A 12-note chroma chart showing which pitches the song leans on • Alternate keys it could also be Who it's for: • Singers figuring out if a song sits in their range • Karaoke fans who want the key before they commit • DJs beatmatching and planning transitions • Producers and beatmakers sampling or remixing • Music students and anyone learning an instrument by ear 100% PRIVATE. The tab's audio is analyzed locally, in your browser's memory, and is never recorded, uploaded, or sent anywhere. There are no analytics and no tracking. No sign-up, no account — completely free. (The tab keeps playing normally; the extension just listens in.) Tip: let a clear, instrument-rich part of the song play (a chorus works well) for the most reliable key read.
