Frequently asked questions

What is Chord Randomizer? Chord Randomizer is a free practice tool that generates random chord progressions with inversions, shows each chord on a piano keyboard, and plays it back with a metronome. You can export any exercise as MIDI or save it as a PNG chart.
Who is Chord Randomizer for? It is for pianists, music students, teachers and songwriters who want fresh chords to practise instead of the same four every day. Beginner level uses major and minor chords, Intermediate adds 7th, sus, diminished and altered chords, and Diatonic builds the chords that belong to a key you choose.
Is Chord Randomizer free? Yes. It is free to use with no sign-up. Optional support for Nathaniel School of Music is welcome but never required.
Does it work on a phone or Mac? It runs in your web browser, so there is nothing to install, and the layout adapts to smaller screens. You need an internet connection because the instrument sounds are loaded when you play.
Who made Chord Randomizer? It was made by Nathaniel School of Music, founded by Jason Zac in Bangalore, India. You can find more free music apps at apps.nathanielschool.com.
