完整梳理 9/10/11/12/13 连音的标准分组（3-3-3 / 4-3-3 / 5-3-3 / 4-4-4 / 5-4-4），核心心法是"把多的音往前挤"；新曲子（俏皮风格）要做大 dynamic 对比 + 落实 accent；下周音阶：E major + C# minor。 A full systematization of 9/10/11/12/13-tuplet groupings (3-3-3 / 4-3-3 / 5-3-3 / 4-4-4 / 5-4-4) with the core insight "push extras to the front"; for the new playful piece — bigger dynamic contrast and landing every accent; next week's scales: E major + C# minor.
