[edit] Execution

Octave glissandi are done by maintaining a constant distance between the thumb and finger used to execute them, and shifting the whole hand in the direction of the glissandi. It requires a certain amount of effort to maintain the octave interval.

Due to the positions of the thumbs on the player's hands, octave glissandos are almost always executed upwards with the left hand and downwards with the right. However, exceptions include Balakirev's Islamey, where players are instructed to execute the glissando upwards across 3 octaves with their right hands in the Tempo di Trepak section.

Due to their difficulty, octave glissandos are infrequently used in the piano repertoire, and their inclusion is often used to increase the difficulty of the music.

[edit] Examples

Pieces which do utilize the effect include:

Beethoven's Waldstein Sonata (3rd Movement)
Weber's Konzertstück in F minor
Brahms' Variations on a Theme of Paganini.
Balakirev's Islamey, Oriental Fantasy

[edit] Trivia

Due to the high speed and soft volume of the octave glissandi in Beethoven's Waldstein Sonata, some pianists use two hands to execute the octave glissandi as if it were a scale. Pianist Wilhelm Backhaus is reputed to have played these glissandi as staccato, giving the impression it was played with both hands, when it was actually played with one.^[1]
