Applying a Constant Tempo, Accelerando, or Decelerando

Previous pageReturn to chapter overviewNext page

As an alternative to editing the tempo of a song graphically, you can select some range of the song and enter the exact tempo value from your keyboard. You can specify a constant tempo value for a selected range in the song, or a continually increasing or decreasing tempo (accelerando or decelerando) for the selected range. You can hear a preview of the tempo before you apply it to the song.

prcarrow To set a constant tempo, accelerando, or decelerando for some range of the song:

1.Select a range of the song by holding down the CTRL key and dragging the mouse, as illustrated here:


2.With the mouse, double-click the tempo button in the toolbar:

B8Type "n" for numeric value.

    -- or --

B8Click the Constant Numeric Value applying_a_constant_temp button in the GraphOverNotestm Palette.

    Composer will display the Set Tempo dialog, as illustrated here:


The dialog indicates the range of the song that you have selected, and the current tempo at the start and end of the selected range. The starting tempo is 80 quarter notes per minute, and the ending tempo is 128 quarter notes per minute.

4.Change the "From Location" and "To Location" if you decide to set the tempo for a different range than the one you selected.
5.Enter a value for the Initial Tempo at the start of the selected range.

-- OR --

Use the slider control to change the value.

6.To apply a constant tempo across the selected range, keep the default choice for "Ending tempo is same as initial tempo". To apply a continually increasing or decreasing tempo across the selected range, choose "Ending tempo is different than initial temp", and specify an ending tempo value.
7.Alternatively to steps #5 and #6, select a percentage by which you wish to adjust the tempo in the selected region.  If, prior to entering this dialog box you had use the Tempo Adjustment control, such as illustrated below to temporarily change the playback tempo, then the value in the dialog box for the tempo percentage adjustment will be pre-selected (to, in this example, 75%):
