What it trains
The Foundations Bundle includes Note Reader, Interval Ear Trainer, Scale & Mode Explorer, Chord Builder & Ear Trainer and Rhythm Lab. One license key opens all five in your practice room, and every tool keeps its own progress, settings and practice sets.
- Reading notes on the staff, fretboard and keyboard
- Hearing and naming intervals
- Spelling, seeing and hearing scales and modes in every key
- Building and hearing triads and seventh chords in every inversion
- Reading and tapping rhythms with timing feedback
