Core Features for Serious Musicians • Comprehensive Clefs: Practice in Treble, Bass, Soprano, Alto, Tenor, and Baritone clefs. • All Keys Covered: Work across all 15 major and 15 minor key signatures. • Inversions: Full support for root position and inverted chords. • Audio Playback: Hear what you build—play and arpeggiate chords to train your ear alongside your eyes. • Smart Review: Flag difficult questions and keep a dedicated list for focused review sessions. • Track Progress: Monitor your accuracy and growth with detailed performance reports.

However, if you want to train chord analysis in any key besides C major you have to pay for a monthly subscription. That’s ridiculous. I understand advanced study features being in a subscription, but other key signatures is silly. Other keys are a part of music, not just C major. -- Bunny of glove, 2024-11-08 ### ***** "Simple yet effective" This app is a great way to learn your chords. It is simple, robust and well written, and has positive comments when you start it up. -- Bangbangboogie, 2023-01-10 [View all Harmonic Analysis reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## Harmonic Analysis In-App Purchases | Item | Price | |------|-------| | Premium Access Monthly | $2.99 | | One-time Payment | $119.99 | | Premium Access Yearly | $29.99 | ## Harmonic Analysis Discovered Keywords -
