Hear a sequence of musical notes, then click them in order on a piano, guitar, or treble-clef staff. Three instruments, melody-snippet bonus rounds, and interval feedback on every miss.
Tone Knowledge is a free ear-training game. A short sequence of musical notes plays, then you click them back in order on a virtual instrument · piano, guitar, or treble-clef staff. Miss one and the run ends. Build the longest streak you can.
Three instruments, one pitch pool. Every round picks from the same 24-note chromatic table (C4 through B5), but the surface you click on changes how you hear and reach for each note. Piano is the fastest to recognise. Guitar adds the fret/string twist · multiple positions can produce the same pitch, so the click is checked on pitch not finger placement. Staff is the hardest · click at the line or space height to pick a note, training sight-reading and ear together.
Melody bonus rounds. Some rounds aren't random sequences · they're transposed snippets of recognisable folk and public-domain melodies (Twinkle Twinkle, Ode to Joy, Für Elise opening, Mary Had a Little Lamb, ...). The melody name is revealed in the post-round explainer · pure pitch memory + pattern recognition together.
Difficulty raises the floor. At low difficulty you get 3 white-key notes, slow tempo, and note labels printed on the keys. At expert the sequence is 10 notes spanning two chromatic octaves at fast tempo, the labels disappear, and the round can land on any of the three instruments.
Interval feedback on miss. When you play the wrong note, the explainer tells you what you played, what the target was, and the interval between · "you played E4, one semitone below F4 (minor 2nd flat)." Turns every loss into ear training.

Q: How does Tone Knowledge work?
Press Listen to hear a short sequence of musical notes, then click them in order on the virtual instrument. The first wrong note ends the round. Your longest streak is saved locally.
Q: Which instruments are available?
Three: piano (white + black keys, click or keyboard), guitar (six strings × twelve frets), and treble-clef staff (click at the line or space height to pick a note). Easy difficulty stays on piano; expert mode rotates between all three between rounds.
Q: What are melody rounds?
Roughly a quarter of low-difficulty rounds, rising to three-quarters at expert, are transposed snippets of recognisable melodies · Twinkle Twinkle, Mary Had a Little Lamb, Ode to Joy, Für Elise opening, and others. The melody name is revealed in the explainer at the end of the round.
Q: Do I need to read music?
Not for piano or guitar · those show note names by default at low difficulty. The staff variant teaches you to read · sharps and flats are drawn next to the notehead, and the row tells you the note. Labels disappear at high difficulty so you build pitch recall, not reading skill.
Q: Can I play without sound?
You can, but the game leans on hearing the sequence · without sound it degrades to reading the note names off the explainer. Turn sound on for the real experience. The shared PlayMemorize sound toggle controls it.
Q: Is it free?
Yes, completely free. No account, no ads, no paywalls. Your high streak is stored locally in your browser and Tone Knowledge works offline as part of the PlayMemorize Progressive Web App.
