This is a learning tool and game designed to allow you to focus solely on studying "note names." * You can play in 3 modes for each category. 1. "Learn" mode, where you learn by pressing the keys manually while auto-playing. 2. "Practice" mode, where you practice with the goal of achieving a 10-combo. 3. "Challenge the Rankings" mode, where you can earn higher scores. * Also, try using the "Hall of Fame" to display your name! * In 1:1 battles, two players can take turns playing together. This makes practicing note names more exciting. * There is also a performance feature where the accompaniment (chords) plays automatically when you press the keys while looking at the note names on the sheet music. * There is a separate administrator (teacher) page where you can save detailed data and reports of participating players as CSV or PDF files. * Character Introduction 1.
