## What is Accorduon?

Accorduon turns iPhone Duo into an accordion: the hinge is the bellows. Fold and unfold to play. No foldable? Rock any iPhone like a steering wheel.

YOUR FOLDABLE IS AN ACCORDION
Hold iPhone Duo open like a book: keys under your left thumb, bass buttons under your right, and the hinge between them pushes air through the reeds. The faster you move, the louder and brighter it plays.

NO FOLDABLE? ROCK TO PLAY
On any iPhone, turn it sideways and rock it like a steering wheel to work the bellows. Or drag the bellows with a finger, or turn on Auto Air to keep them full.

REEDS, NOT SAMPLES
Every note is synthesized as you play: three musette reeds beating against each other, a bassoon reed below, the wooden chamber and the hiss of air.

SIX REGISTERS
Flip the switches like on a real accordion: Master, Clarinet, Bassoon, Bandoneon, Violin and Musette.

9 SONGS TO PLAY ALONG
Follow the notes key by key: Ode to Joy, Twinkle, Twinkle and Happy Birthday, plus six more with Pro: Jingle Bells, Frère Jacques, When the Saints, Oh! Susanna, Amazing Grace, Korobeiniki.

MAKE IT YOURS
Keys on the left or right, note names, haptics.
