About this app

Figured bass is the number shorthand under a bass line that tells a player which chords to build — the working language of Baroque harmony and a core skill in music theory and harmony exams.

Figured Bass Trainer shows you a real chord voiced on the staff. Your task: choose the correct figure — 5/3, 6/3, 6/4, 7, 6/5, 4/3, 4/2 — including altered figures with slashes, sharps and flats. Every answer gives instant feedback, so you learn the reasoning behind each chord position as you go.

PRACTICE THAT ADAPTS
• Three difficulty levels: unaltered figures, the full mix, and altered figures with accidentals
• Weak-area detection finds the figures you miss most and drills them
• Mistake review rebuilds a session from the chords you got wrong
• Exam mode: a 20-question practice test with a complete answer review

BUILD THE HABIT
• Daily goal and streak tracking keep you practicing
• Progress history and detailed statistics
• Works offline — practice anywhere
