Piano Chords: Keys + Accordion

There were no apps to play melody with chords on the phone, so I made this one! Play music on your phone, both melody and chords at the same time! Among many piano apps in the store, this one makes it easy to play your melody with accordion chords.

Use your right thumb to play the melody, and use your left thumb to play chords using the buttons conveniently located in the top left of the screen. Or convert it to the chord only keyboard by switching a toggle in settings!

If you are using a laptop, press Space to see the key bindings to play using your keyboard.

Features

• Large Piano Keyboard: Designed for being usable when you play with your fingers on your phone
• Laptop Keyboard Support: Press Space to see the key bindings
• Stradella Chord Keyboard: Inspired by accordion buttons, to add chords to your melody
• Five Rows of Accordion Buttons: Bass, counter bass, major chord, minor chord, and major seventh chord
• Circle of Fifths Arrangement: Notes are arranged following the circle of fifths, making related chords easy to find
• MIDI Recording: Record your melody and share it with your friends in MIDI format

How It Works

The left hand section has several rows of buttons, each of which are arranged in the circle of fifths, which is called Stradella bass system. It takes just a few minutes to realize that this is extremely useful for playing chords, because related chords are located near each other: if you take C major, then F major is on the left, and G major on the right; if you take A minor, then D minor is on the left, and E major on the right.
