Music pitch changer

A music pitch changer lets you raise or lower the key of a song instantly.
Singers use it to match their vocal range, guitarists to practice in new keys, and learners to slow down and repeat tricky passages.

With the free Transpose extension, you can change pitch in real time while streaming from YouTube, Spotify (web), SoundCloud, Deezer, and Apple Music.
