Take a look inside
Six workspaces, on one screen.
Chordio brings its full set of workspaces to iPad, so you can compose, explore and study wherever inspiration strikes.
Composition
Sketch a progression with your finger.
Drop chords onto the canvas, edit voicings and inversions, then play the whole thing back with a sequencer.
Scales
A whole library of scales to explore.
Tap a root or a scale type to move between scales fast, and practise each one against the built-in metronome.
Modes
Rotate the circle of fifths.
Coloured areas show which chords sit close together, so you can see the smooth moves before you hear them.
Sheet Music
Prop it on the music stand.
Slow the tempo, loop the tricky bars or transpose the score — then play along from the iPad itself.
Lessons
Follow the playhead, bar by bar.
Slow a lesson down or shift its pitch, scroll through any passage, and capture the chords you want to master.
Anywhere
The studio goes where you go.
On the sofa, at the piano or on the train — the full composition and theory studio travels in one hand.
MIDI keyboard
Connect a MIDI keyboard.
Connect a compatible USB MIDI keyboard to your iPad or Mac to play instruments, practise scales or solo over a chord progression. You can also use a Bluetooth MIDI keyboard for a wireless, flexible setup.
Real-time chord symbols and related scales as you play
Practice makes perfect — learn to play any piece your way. Chordio offers interactive lessons that can be slowed down, looped or transposed to fit your needs. Jazz musicians can also use the built-in backing tracks for improvisation and exploration.
Most Western music is written in a key, using notes from a particular scale. Tap a root note or a scale type to move through Chordio's collection — an essential tool for any musician.
Learn any piece, at your own pace.
Practise slowly and build up. Slow a lesson down or change its pitch, scroll through any passage, and capture the chords you want to master.
Made for touch
Drag chords, tap notes on the staff to hear them, and play the on-screen keyboard with both hands.
Wired or wireless
Connect a USB MIDI keyboard, or go cable-free with Bluetooth MIDI for a flexible setup.
Print-ready PDFs
Export chord sheets and scores as PDFs for the music stand, the band or the class handout.
One purchase, every device
Take your workspaces anywhere.
Chordio for iPad puts the full composition and theory studio in your hands. Sketch an idea
on the sofa, practise sheet music at the piano, then pick up right where you left off on
your Mac — it's the same app, and a single purchase covers both.
