Harmony at a Glance

An A3 wall chart of the seven chords of a major key shown in C with roman numerals, the four cadences, chord inversions and figured bass, the three chord families, and six progressions that work.

What's inside

• The seven chords of a major key shown in C with roman numerals, names and quality — from I (tonic) to vii° (leading note)
• The four cadences — perfect, plagal, imperfect and interrupted — each shown in notation with what makes it sound the way it does
• Inversions and figured bass, from root position through second-inversion seventh chords, plus the cadential six-four
• The three chord families — tonic, subdominant and dominant — and the rule that harmony moves forwards through them
• Five progressions that work, from the plain I–IV–V–I loop to the ii–V–I jazz backbone, plus panels on writing numerals, minor-key harmony and harmonising a melody
