Piano Chords: keys + accordion
Keyboard and Stradella buttons
Free · In‑App Purchases · Designed for iPad
Play both melody and chords in this app!
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!
I like being able to play a melody on my phone, and I could not find an app which makes it really easy, so I made my own. Play your melody on a large piano keyboard, designed not for being visually appealing, but for being usable when you play with your thumbs. Use the Stradella chord keyboard, inspired by accordion buttons, to add chords to your melody.
Five rows of accordion buttons are available: bass, counter bass, major chord, minor chord, and major seventh chord. Notes are arranged following the circle of fifth.
If you have never played accordion, you should try! The left hand section has several rows of buttons, each of which are arranged in the circle of fifth, 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.
Look at the provided demo melodies and you'll be playing your own music in no time!
You can also record your melody and share it with your friends in a MIDI format.
I hope you enjoy the app!
