Core chords and inversions
Learn I, IV, V and vi with close voice leading, bass notes, scales and secure changes in C, G and F.
Chord training from first steps to jazz
Everything you need to learn piano chords
Connect your MIDI keyboard and learn by playing. Get feedback on every note, follow a clear course path and see exactly what becomes more secure over time.
AmCorrect!
The app recognises chords, inversions and wrong notes instantly – regardless of which MIDI keyboard you use.
One connected course path
The courses begin with chords that let you play songs early and build from there. The main path shows your next step, while the key track is ready when you are.
All twelve keys
Move the same knowledge around the circle of fifths and practise scales, diatonic chords and familiar progressions in every key.
Accompaniment and groove
Play pop, ballad, 6/8 and waltz with pulse, pedal, dynamics, intros, turnarounds and endings.
Numbers and transposition
Read Nashville numbers and Roman numerals, change key and transpose without relearning the progression.
Minor keys
Play minor keys, harmonic minor, dominant chords and ii–V–i with a clear function for every chord.
Seventh chords and jazz voicings
Continue with maj7, m7, 7, m7b5, ii–V–I, shell voicings and rootless left-hand voicings.
From exercises to complete songs
The chord sheet follows your place as you play. Practise slowly, play in tempo or add a backing part – with support for intros, form, dynamics, pedal, key changes and a clear ending.

Practice adapts to you
The app stores structured results from your playing and uses clear rules to choose the next exercise – not guesses.
Your keyboard range
Exercises, notation, fingering and answers move together to fit your MIDI keyboard, from compact to full-size instruments.
Your notation
Choose standard chord symbols, Nashville numbers or Roman numerals. You can also choose B or H note naming.
Notation and fingering
See staff notation, hand split and fingering suggestions for both hands. Display, sound and grading all use the same answer.
Review and free practice
Review prioritises material you forget or confuse. Free practice removes time pressure and stars.
Statistics that show more than a score
Follow what you can actually play, how quickly you find each shape and where mistakes happen.

Personal advice with controlled AI support
The app's own tested logic selects your weakest chords and transitions. The AI coach receives only a summary of the statistics and explains why the suggestion matters and how to practise it.
What should I practise today?
Coach
Nice! Am now takes you under a second. The F → G change is still your slowest. Spend five minutes on just that change today and you'll feel the difference tomorrow.
