About the ii-V-I Progression
The ii-V-I is the most fundamental chord progression in jazz. It consists of a minor 7th chord built on the second degree, a dominant 7th on the fifth degree, and a major 7th on the tonic. This progression appears in virtually every jazz standard and provides the harmonic framework for countless compositions.
Who Is This For?
These flashcards are essential for jazz musicians at all levels—pianists, guitarists, horn players, and vocalists. Whether you're learning jazz for the first time or refining your ability to recognize progressions instantly, this tool builds the foundation for understanding functional harmony.
How to Practice
Focus on recognizing the quality of each chord relative to its function. The ii is always minor 7th, V is dominant 7th, and I is major 7th. Practice until you can instantly name the missing chord without calculating. Use challenge mode to simulate the quick recognition needed during performance.
Common Challenges
Students often struggle with keys that have many sharps or flats. Remember that ii-V-I relationships are consistent—once you know the key, the chord qualities follow automatically. Practice the trickier keys (B, F#, Gb, Db) until they feel as natural as C major.
