Each game has a "Cross-Examination ~ Moderato" (尋問 ～モデラート) the and a "Cross-Examination ~ Allegro" (尋問 ～アレグロ) theme which play during witness testimonies and cross-examinations. In each game, the "Allegro" theme is a faster, more intense and usually extended remix of the "Moderato" theme; "Moderato" plays during earlier testimonies and "Allegro" during later testimonies, when the trial chapter is approaching its climax.
In Apollo Justice: Ace Attorney, a third variation of the local "Cross-Examination" theme is played when Apollo Justice uses his bracelet: "Perceive ~ Surge, Eyes" (みぬく ～ほとばしれ、視線). Ace Attorney Investigations: Miles Edgeworth also had a third variation, "Presto", which is typically used for the final testimony in each case, with two exceptions. This theme is used again in Gyakuten Kenji 2, albeit this time with four exceptions.

Moderato, allegro, and presto are all terms used in musical scores to describe at what tempo (speed) the music should be played; moderato for a moderate tempo, allegro for a quick/lively tempo, and presto for a very quick tempo. Each "Cross-Examination" theme in the Ace Attorney games follow their respective tempos.
