There are many songs that share the same chord progressions and, in some cases, even the tempo. Often a lot of work goes into making the song simple yet distinct by arranging or sound design.
The core of a song, the main idea, are the chords, and the melody. Why do we use Roman numbers to refer to as chords? You also can have the same chord progression as many known songs do, but with a different melody, for example, you will end up having a whole different song. We use Roman numbers to change the tonality and have the same progressions going on in a different key.Įvery song is in a specific key, a tonal center that all of the other chords revolve around.
