TwelveKeys

TwelveKeys is an ideal program for music lovers who want to know how to play their favorite songs without an advanced knowledge of music.

This application seeks to analyze the song you choose, to find the musical notes that make up the melody, and visually show us the score, so that you have a rough idea of how to play the song.

To use it, you just have to open an audio track and play it. You can select any point on the recording to start, so if you just want to know how to play a part of the song, you can do it quickly.
