Learn how musical notes move from low to high, one step at a time! Choose between the Treble Clef and Bass Clef, then drag each note to the correct line or space on the staff. In Treble Clef mode, students practice from C4 to A5. In Bass Clef mode, they practice from A2 to E4. Every correct note adds a new part to the music house, while incorrect answers cost a heart and give students another chance to try. Complete the full note sequence to finish building the house and strengthen note-reading skills.
