Frequently asked questions

How does StrumTube extract chords from a YouTube song?

We analyze the video audio using pitch and harmony detection: we separate the harmonic layer, estimate the key and tempo, and map each bar to a chord with its timestamp. The result is synchronized with playback.

Does it work for ukulele as well as guitar?

Yes. Every chord includes diagrams for 6-string guitar and GCEA ukulele, and you can switch instruments without losing your place in the song.

Can I change the key or use a capo?

You can transpose the song semitone by semitone, and StrumTube suggests which fret to put the capo on so you can use simpler open shapes.

Do I need to read sheet music?

No. You work with chord diagrams and a bar-by-bar timeline just follow whichever chord lights up.

Is a tuner included?

Yes, the chromatic tuner uses your device's microphone and shows the deviation in cents for guitar and ukulele.

Is StrumTube free?

Yes StrumTube is completely free. Search songs, view chords, and use all features at no cost.
