Shape the exercise
A soft chime means correct and a low tone means try again. Your keyboard's own sound is unaffected.
Keyboard connection Devices & troubleshooting
- No MIDI keyboards found yet.
Connect a digital piano or MIDI keyboard by USB (or a USB MIDI interface) before or after opening this page, then select Connect keyboard and allow MIDI access. New devices are detected automatically after that. The browser remembers your choice for the website, so later visits reconnect without asking.
Web MIDI works on secure (https) pages in current Chrome, Edge, and Opera (desktop and Android) and in desktop Firefox. Safari and iOS browsers do not support it; use the on-screen keys there. Some built-in app browsers, such as the one in VS Code, block MIDI entirely, so open the page in Chrome or Edge instead. If nothing responds, close other music apps that may be holding the keyboard, reconnect the cable, and check the browser's site permissions for MIDI devices.
Practice guide How the exercise works
How a round works
Select Start and a random note appears. Play it anywhere on your keyboard; every octave counts. A correct key shows a green tick, plays a soft chime, and the next note follows a moment later. A wrong key shows a red cross, plays a low tone, and tells you which note you played, so you can try again. Turn off Sound cues for silent practice. Skip reveals the answer on the on-screen keys and moves on.
Find notes by pattern
Black keys sit in groups of two and three. C is the white key just left of each group of two; F is just left of each group of three. Locate those anchors first, then count up or down to nearby notes instead of reading key by key from the left edge.
Sharps and flats
A sharp (♯) is the next key to the right, and a flat (♭) is the next key to the left. Each black key has two names, so C♯ and D♭ are the same key. Choose sharps, flats, or both to practise whichever names your music uses.
Score and shortcuts
Accuracy compares correct keys with every key you played during the round; skips do not count as attempts but do end your streak. Average time measures from a note appearing to the correct key. With focus outside a form control, Space starts or stops and N skips. The on-screen keys also answer, which is useful without a keyboard.
What is shared?
Note messages from your keyboard are read only by this page while it is open. Nothing you play is recorded or sent to a server, and no system-exclusive MIDI access is requested. Your exercise settings (note set, naming, round length, and sound cues) are remembered in this browser's local storage; scores are not saved.
