Song Key Finder: The 5 Best Software to Find Song Keys (Windows 10)

Music is written in key. The ‘key’ is a technical term that defines the pitch and scale of sound in music or in song. If you only ever listen to music, this may not matter to you much but if you record music, or work with it in any other form, it’s basic knowledge you should have.

The key of a music helps determine its mood i.e., is the music soft, is it uplifting, it is active, is it morose, etc. If you’ve trained your ear to recognize the key of a song or piece of music, you can identify it by playing it but for a large library of music clips, it’s better to automate the process using a key finder.
