L'istesso tempo

The same tempo. An indication in a composition that directs that the beat remains constant when the meter changes. In the case of 2/4 to 6/8, the meter is still counted with two beats per measure but the tempo or speed of the beat stays the same. All that has changed is the subdivision of the beat from the duplets of the 2/4 to the triplets of the 6/8.See also Lo stesso tempo.
