Constantly repeating. The repetition or repeated striking of a single note by means of a special mechanical or pneumatic action built for this purpose or by means of closely-spaced holes in a music roll or music book. When an extended hole appears in the music roll (or when a staple-like bridge pin occurs in a pinned cylinder arrangement) the reiterating action will constantly repeat the note until the perforation has ended. * Synonym: repeating.
