Transpose songs and chords
the easy way with Key Switch!

• Transpose songs to any key using our online chord transposer, here at TheoreticallyCorrect.com

Just copy, paste, transpose and save.

——  Public Beta online now  ——

• Key Switch chord transposer works with:
  • lyrics and chords from your word processing documents
  • song sheets that you find on web pages
  • any chords and lyrics you type or paste
  • Key Switch does not allow you to change the pitch of an audio recording (not yet anyway.) If you want to change the pitch or speed of an audio recording read this article about Transcribe!

• To change keys with Key Switch you don't have to understand music theory, scales or keys.
• Once you've got the initial key set, any other key is a single click away.
• Transposer will intelligently guess to determine the original key—and it's pretty good at that—so usually you just need to know the name of the key you want to transpose to.
• If you already know how to transpose music, Transposer will save you time ... and it eliminates those pesky, inevitable errors. Just get it done.
• Transpose alphabetical chords (like D G A) to Roman numbering (I IV V). Or do the opposite: transpose from Roman numbering to any key.

Example transpositions:

• Click to see Wayfaring Stranger before and after transposition, and see it transposed to Roman numbering.
• Here's Slumber My Darling before and after transposing.

• Transpose guitar chords, any chord progression, chord collection, or scale. Type or paste in chords, and lyrics if you want. Choose the new key, and you're done.

"Don't even think about it. Just transpose it!"
