What it does
01
A composing engine of music theory alone, with no training data
Unlike AI composing so far, it uses no training data. MusicFlow’s engine builds each solo by the rules of music theory alone. Even the same song has new phrases every time you listen.
02
In My Room — at home
Bring chord changes in from iReal Pro and Pianoman solos over them. You can play a theme of your own on the keys, too.
03
On the Street — listen together and like
The street piano holds songs everyone can hear. Like the ones you love; each song shows everyone’s likes.
04
Your song can debut On the Street too
Post 30 seconds of a song you gave a theme in In My Room, with Pianoman’s video, to social media. People who open it there hear it in Pianoman, and it lines up On the Street.
05
Play favorites, and on it goes
[Play favorites] plays your liked songs in random order, then goes on to On the Street and In My Room.
06
Tones, halls, and night
Choose the piano’s tone and the hall it plays in. Night mode plays relaxed, and follows your appearance setting when it is set to Automatic.
07
The glass piano
The upright’s front board is glass: you can see the hammers strike the strings. Behind the glass is the back camera’s view (nothing is saved or sent). While playing, the camera button turns it on and off.
08
A grand piano in 3D
On iPad and iPhone, watch a grand piano in 3D as it plays. Turn it with a finger to any angle.
Made for iPhone Duo
On iPhone Duo, the piano changes with how you hold it.

Open like a notebook
