iChords is a harmony transcription software. It recognizes chords in audio files (MP3, WMA, WAV and CDs) and presents them on a virtual guitar or keyboard. You'll be able to see the chords of any song, without having to search for tablatures and sheet music. Easy to use, just open a song file and iChords will process and extract the chords, while playing the song it shows the current chord and the next ones with fingering, notation or intervals.
