Chordzy help answers what goes wrong with the piano app and the website: a keyboard the browser cannot see, a sound you did not pick, a jam that will not connect. Something not working quite right? Pick the group below that matches it. If none does, the [contact page](/contact) reaches the people who build Chordzy.


## Hardware

Chordzy needs a MIDI keyboard to grade what you play. Microphones and web cams matter only for jams in the desktop app. [Hardware](/help/hardware.md) compares what works where.

## Jams

A jam connects your computer straight to another player's, the way some video games do, and needs the desktop app on both ends. Home routers, Wi-Fi and phone data can each get in the way. The connections page explains every error message a jam shows and what to change.

## Synthesizers

The synthesizer turns the keys you press into sound, from a grand piano to a bagpipe. These pages cover which sounds come built in, how to put one on your keyboard, and which MIDI features the synth ignores, such as the sustain pedal.
