Sequenza XII is the longest of all the Sequenze, at 19 minutes. As with the other works in the series, it reflects Berio's fascination with virtuosity, "understood not merely as technical dexterity, but as a manifestation of an agile musical intelligence that relishes the challenge of complexity" (Osmond-Smith 2001). In Sequenza XII, Berio makes deliberate use of the different registers and explores the physical limits of performance through extended techniques, for example, through different uses of the tongue to modify airflow, by writing notes and phrases that are so long they require the performer to use circular breathing, the use of glissando, and multiple sounds producing by singing through the instrument while playing (Osmond-Smith 2001; Pedone 1997).
