First, you need to understand how to write seventh chords like this one. To write a seventh chord, you take a simple triad like this and add this one note. If your triad is a major triad, your 7th will be 11 half steps above your root note. If your triad is minor, the 7th will be only 10 half steps above that same note. You only need two of these seventh chords to make Lofi Music’s most common chord progression. We’ll start with a major seventh and follow with a minor seventh, just two half steps above. If you want to switch it up, you could choose a different minor seventh chord, like maybe this one or this one. And you could even play the minor chord first, just so long as you resolved whichever chord you put in the first slot.
