| Gradual change of values over time | To specify the gradual change over time of the characteristics of an event, such as music tempo. |
Many types of music events change gradually over time. Some of these types of events are tempo, volume, sound texture, effects, and so on. Here gradual change in tempo is explained.
Music may gradually slow down or increase in pace. One should be able to mark the starting point of the gradual change in tempo and the end point. Electronic devices should be able to calculate the gradual change.
The gradual increase and decrease in tempo are indicated with numerical values of the gradual attribute. The specified value should be the target value. The bar number at which the target should be reached is indicated with the target attribute.
| Markup | What happens... |
|---|---|
| <bar 26 tempo="105" gradual="120"
target="30"> ... <bar 50> |

| <bar 26 tempo="105" gradual="95"
target="30"> ... <bar 50> |
The music has to gradually decrease in tempo from bar 26 to 30 |
