Gradual tempo changes
Gradual tempo changes indicate a change in tempo over a defined period of time, such as rallentando, which indicates slowing down, and accelerando, which indicates speeding up.
Gradual tempo changes are considered a type of tempo mark in Dorico Pro, meaning you can input them in the same ways as for tempo marks.
Because gradual tempo changes have a different metronome mark value at the start/end, you can change the final tempo at the end of individual gradual tempo changes.
In Dorico Pro, you can show gradual tempo changes with different styles, such as with a continuation line or with syllables spread across their duration. You can also show gradual tempo changes with different line styles, such as dotted or dashed.
