Efficient Piano Chord Triads

Ideal for the piano student focused on learning the primary chords for each scale, and their inversions, and to switch between them efficiently.
Select a Key and mode from the drop down. Scales/Modes covered are Major, Minor, Harmonic Minor, Dorian, Phrygian, Lydian, Mixolydian, Locrian. The common key representations are chosen for brevity (C# instead of Db, Bb instead of A#, etc.)
Each of the main triad chords for the seven intervals in the selected key/scale will be presented on the staff. The chord fingering chart is also presented for each chord including their first and second inversions.
To learn to switch between chords efficiently, just tap a chord and the most efficient fingering for each chord in that key will be highlighted.
Ex. Select C Major, Dm and Bdim will be highlighted, along with inversion1 of G and Am, and inversion 2 of Em and F, as moving from C Major to any of these fingerings would be efficient. If you want to stay in the key of C Major, but would like to know the most efficient fingerings from the first inversion of G, just tap the first inversion of G and the most efficient chord options will be presented.
