How many exercises does PianoKitty have?
Short answer: a LOT. We'll show you the big number first, then explain where it comes from.
How big is that, really?
More than seconds since the Big Bang
The universe is about 13.8 billion years old — roughly 430 quadrillion seconds. PianoKitty has about 160 000 times more exercises than that.
More than grains of sand on Earth
All the beaches and deserts together hold about 7.5 quintillion grains. PianoKitty has roughly ten thousand times more exercises.
Way less than atoms in your body
Your body contains around 7 × 10²⁷ atoms — that's still about 100,000 times more than our number. So we're huge, but we're not infinite.
What makes them all different?
An "exercise" is one practice round. PianoKitty lets you mix-and-match a bunch of things to build one. Here are the main ones:
50+ chord types
Some chords sound bright (major), some sad (minor), some weird and crunchy. PianoKitty knows fifty different flavors, and you can pick which ones to practice — alone or together.
12 keys
Every chord shape can start on twelve different notes — like the same drawing in twelve colors. Practice one, or shuffle them all.
20 scale types
Major, harmonic and melodic minor, modal scales (dorian, mixolydian, phrygian…), pentatonics, blues, bebop, and chromatic — practice the scales your style needs.
4 inversions
You can play the same three notes in four different orders. Each one feels a bit different under your fingers, and sounds a bit different too.
4 hand modes
Left hand, right hand, both hands, or whichever — you decide who's working in this round.
Tempo & playback
Slow enough to think, fast enough to sweat. The metronome goes from "taking it easy" all the way up to "showtime".
Will I ever run out of new exercises?
Nope. Even if you played a brand-new exercise every single second for the rest of your life, you'd only see a tiny corner of what PianoKitty can build. There's always something new to try.
Even if we only count the exercises that actually make musical sense for a learner, the number is still around 50–100 million. You'll never bump into the edge.
Looking for a particular exercise?
Your favorite musician, friend, piano teacher, or YouTube guru just told you to practice something specific — maybe "minor seventh chords in every key", or "right-hand triads in second inversion", or "the C major scale, slow, both hands". What's the chance PianoKitty can actually set that up for you?
Almost always yes. PianoKitty doesn't ship a fixed list of lessons — it builds exercises by mixing your choices. Pick a key, some chord flavors, an inversion or two, your hand, and a tempo, and that's your exercise. Almost any reasonable practice drill someone might recommend maps right onto those knobs.

How do we know? (the math)
We just multiplied the choices together. Each row below is one knob you can turn; the final line is everything multiplied at once.
- Chord-type combinations (50 flavors, mix-and-match)
- ~1.13 × 10¹⁵
- Keys / base notes (12 each)
- 12
- Inversion combinations (4 inversions, mix-and-match)
- 15
- Voicings (single notes, triads, sevenths, intervals…)
- 16
- Hand modes (left, right, both, any)
- 4
- Useful tempo presets
- ~10
- Playback sequences (random, in-order, …)
- 10
1.13 × 10¹⁵ × 12 × 15 × 16 × 4 × 10 × 10 ≈ 7 × 10²²
Multiplying it all together lands around 7 × 10²² — that's our "70 sextillion". Most of the explosion comes from chord-type mixing: you can build over a quadrillion different chord menus on its own.
And realistically?
If we throw away nonsense combos and keep only pedagogically useful ones, we're still looking at roughly 50–100 million human-friendly exercises. PianoKitty's job is to pick the right one for you next — that's what the suggestion engine on your dashboard is for.
