How is l’istesso tempo played?
At the notational change, identify which beat or temporal unit is meant to stay equal and carry that physical duration into the new metre. In the common change from 2/4 to 6/8, two beats remain in each bar, so the old quarter note normally equals the new dotted quarter note; other historical examples preserve a measure or a different note value instead. Do not assume that every printed note value stays identical, and do not treat the marking as a fresh accelerando or ritardando. The relation takes effect at once and remains until another tempo or metronome instruction changes it. This traditional instruction anticipates the idea of explicit metric relationships, but it normally preserves continuity rather than creating Carter-style tempo modulation.
How does l’istesso tempo sound?
The pulse continues unbroken and the music feels metrically seamless, even though the page reorganises how that pulse is grouped and counted.
In context
Historical dictionaries illustrate l’istesso tempo with Beethoven’s Op. 111, 119, 126, 110 and 120, showing that metre, measure and note-value relationships can change in more than one way while temporal continuity is maintained. Twentieth-century notation later made pivot-note relationships explicit in metric or tempo modulation: Elliott Carter systematized that practice, preferred the name tempo modulation, and Richard Franko Goldman coined the widely used metric-modulation label in 1951. The later technique is a historical extension, not an exact synonym for every l’istesso tempo marking.
