Notes of the Black Piano Keys. Black piano keys are called accidentals; these are the sharps and flats of the piano. On the keyboard, there are five black accidentals per octave. A sharp makes a note a half step higher in pitch. A flat makes a note a half step lower in pitch. On the keyboard, a noteâs flat is the black key directly to its left.
Grand Jury. Federal jurors are paid $40 a day. Jurors can receive up to $50 a day after serving 45 days on a grand jury. (Employees of the federal government are paid their regular salary in lieu of this fee.) Jurors also are reimbursed for reasonable transportation expenses and parking fees.
What Grand Juries Are. A grand jury is a group of ordinary citizens that is tasked with investigating suspected criminal activities and deciding whether to issue indictments, which are more commonly known as criminal charges. The grand jury can consist of up to 23 people, but there are often fewer. Technically, federal judges impanel the jury. However, as a practical matter, federal prosecutors control the process from beginning to end. A grand jury can subpoena witnesses and documents.
