    速度记号可以在基础和进阶工作区的速度符号面板中找到。他们被作为节拍符号提供,但随后也可以被编辑,直至表达出您想表达的速度与表情。通过使用多种可见或不可见的速度记号,播放速度在乐谱的任何位置都可以变化。

    添加速度记号

    使用如下任何方法之一:

    • 选择一个音符或休止符,并按下__键盘快捷键__Alt+Shift+T
    • 选择一个音符或休止符,并从菜单栏中选择 添加Text...速度记号
    • 选择一个音符或休止符,并点击速度符号面板中适当的速度记号(在3.4版本之前需要双击);
    • 直接将速度符号面板中的速度记号拖动并放置在一个音符或休止符上。

    注意: 如果一个速度记号是通过菜单或键盘快捷键布置的,则该拍音会自动遵循拍子记号。从符号面板配置速度记号的优势在于您可以自由选择您想使用的拍音。

    编辑速度

    调整乐谱上一个速度记号所代表的速度的方法:

    1. 在想改变的速度符号中进入编辑模式
    2. 按照需要的节拍数和/或拍音进行编辑;
    3. 退出编辑模式。

    您也可以从检视器中覆盖一个已存在的速度记号的速度:

    1. 选中想修改的速度记号;
    2. 检视器速度文本模块中取消选择“随文本改变”选项;
      Inspector: Tempo Text
    3. 在“速度”栏中选择您想使用的播放速度。

    注意: 如果播放面板中的速度设定不是100%,播放速度可能会更快或更慢。

    Edit tempo text

    Tempo marks can be edited and formatted just like any other text object. To set text properties or text style, see Text styles and properties.

    The tempo indicated by a metronome mark usually persists even if overwritten by an expression—such as Andante, Moderato etc. You can also add further text to a plain metronome mark. e.g.

    Metronome mark: Andante quarter note = 75

    Overriding the tempo marking

    You can temporarily override the indicated tempo, and play the score back at any tempo you like using the play panel:

    1. Display the play panel: ViewPlay Panel or F11 (Mac: fn+F11):

    2. Move the tempo slider up or down as required. The tempo is shown both as an absolute value and as a percentage of the currently indicated tempo mark. Double-click the tempo slider to reset it.

    Note: BPM is always measured and displayed in quarter note beats per minute, regardless of the (denominator of the) time signature in effect.

    Ritardando and accelerando playback

    You can simulate ritardando ("rit.") and accelerando ("accel.") playback by adding hidden tempo markings to the score. The printed indication to the musician should be added as staff/system text in addition.

    In the example illustrated below, the tempo was originally 110 BPM (beats per minute). At the ritardando, the tempo decreases by 10 BPM on the first note of each measure. Each tempo change is made invisible by unchecking the Visible checkbox in the Inspector, so that only the ritardando shows on the printed score:

    A plugin has been developed to automate this process: TempoChanges

    Fermatas

    Fermatas, available in the Articulations and Ornaments palette, have a Time stretch property that can be set via the Inspector. By default, this property is set to 1.00. To have MuseScore play back a fermata for twice its normal duration, click on the fermata and set "Time stretch" to 2.00. This of course does not work for fermatas applied to barlines, as barlines don't have a duration to stretch.
