Bossa Nova Guitar Chords: Minor 7th Chords  The darker and moodier cousin of the major 7th chord, minor 7th chords (m7) have their own distinct voice.  Made up of the I – bIII (minor 3rd) – V & bVIII (minor 7th), this brooding combination of notes is a great addition to our vocabulary of Bossa Nova guitar chords.     

Many Bossa Nova tunes (more commonly known as Bossas) take place in a minor key, which means
you’ll be relying on minor 7th chords quite a bit in this style of music.
