如何获取大调模式下语法对应的字符

def get_major_scale(root_note, mode):
    # 定义所有大调模式的音阶模式
    major_modes = {
        'Ionian': [0, 2, 4, 5, 7, 9, 11],
        'Dorian': [0, 2, 3, 5, 7, 9, 10],
        'Phrygian': [0, 1, 3, 5, 7, 8, 10],
        'Lydian': [0, 2, 4, 6, 7, 9, 11],
        'Mixolydian': [0, 2, 4, 5, 7, 10, 11],
        'Aeolian': [0, 2, 3, 5, 7, 8, 10],
        'Locrian': [0, 1, 3, 5, 6, 8, 10]
    }
    
    # 获取音阶模式对应的半音偏移量
    scale_intervals = major_modes[mode]
    
    # 生成音符序列
    scale_notes = []
    current_note = root_note
    for interval in scale_intervals:
        scale_notes.append(current_note)
        current_note += interval
        if current_note >= 12:
            current_note -= 12
    
    return scale_notes

# 示例：获取C大调的Ionian模式音符序列
root_note = 0  # C音对应的半音编号为0
mode = 'Ionian'
scale_notes = get_major_scale(root_note, mode)
print([note % 12 for note in scale_notes])  # 输出: [0, 2, 4, 5, 7, 9, 11]
