Read the figured bass, then build the chord above it, and learn every inversion of the same triad along the way.
Was this fun?
How to play
Each challenge shows a bass note plus a figured-bass symbol. Your job is to stack the correct chord tones above that bass on the on-screen keyboard, then submit. A round walks the same diatonic triad through all three positions so you internalise root, first and second inversion.
Play the bass and figure to know which triad is implied
Click the keys that complete the chord above the bass
Submit a correct stack to clear the challenge and move on
Use a hint if a voicing has you stumped
Controls
Desktop: click piano keys to add or remove notes; use the Clear, Hint and Submit buttons
Phone & tablet: tap the keys and buttons, the whole interface is touch-driven
Tips & strategy
Find the root from the figure first, then spell up in thirds
Remember the bass is fixed, you are choosing the notes that sit above it
Lean on the repeated triad: once you voice it in root position, the inversions are the same notes reordered
