TwelveKeys is free software for Windows to assist musicians to transcribe music recordings.

The software creates a visual representation of the notes in any music recording. TwelveKeys is able to accurately detect notes in both simple single instrument recordings as well as complex polyphonic compositions. You can also play the recording at slow speed (constant pitch) or loop short parts of the recording to figure out the more subtle detail when trying to reproduce the music yourself.
