Harmony training: understand where a progression wants to go
Collecting chord names does not explain why one sequence feels settled and another feels unfinished. Harmony training connects construction, context and listening so you can make deliberate choices.
Try the first exerciseThe working theory
Listen to function before adding complexity
In C major, C major is I, F major is IV and G major is V. The labels describe their place in the key. A tonic chord can feel settled; a dominant chord often creates an expectation of return in tonal music.
G7 contains G, B, D and F. Its B and F form a tritone. In a familiar resolution to C major, B can rise to C while F falls to E. Hearing those individual motions explains more than memorizing “V7 goes to I.”
Context matters. A chord can play a different role in another key, and music does not have to resolve every tension. Treat theory as a way to describe and test a choice rather than a rule that forbids alternatives.
Your first experiment
Try it. Listen. Make one change.
- Build C–F–G7–C in ChordForge and listen at a comfortable pace. Hum C before and after the progression to keep the tonic in mind.
- Compare G–C with G7–C. Listen specifically for the added F in G7 and its movement toward E.
- On piano or guitar, play B–F followed by C–E as a two-voice reduction. On bass, outline G to C and sing the upper motion. Drummers can mark the harmonic rhythm with one clear pulse per chord.
Check your understanding
Can you hear the difference between chord quality and chord function? “Dominant seventh” names a chord quality; its role in a particular key depends on context.
Take the idea into the laboratory
Use the Chordcraft Lab for chord construction and function, the Circle of Fifths Reactor for key relationships, and the Interval Reactor for distances between notes. Harmony Navigator and ChordForge let you explore those relationships in tools.
