This app makes it easy to capture taiko rhythms learned through oral recitation and turn them into digital data. With one key press, you can enter two eighth notes (one quarter note), making it the perfect pace for singing or chanting as you input. All data is saved in CSV format, allowing flexible editing inside the app, exporting to other software, or sharing via social media. You can easily combine short sections into full pieces or gather parts into a complete score.
