About Blockly Music
Blockly Music lets kids compose real tunes by snapping note blocks together — pitch, rhythm and loops become a song. Program Frère Jacques, then invent your own earworm.
How to play Blockly Music
Stack note blocks (each with a pitch and length) inside play blocks and press Run to hear your composition. Levels guide you from a single phrase to rounds with multiple instruments playing together.
Questions & answers
- What does Blockly Music teach?
