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.
1 Grand Jurors do not serve on a trial, like Trial Jurors. Rather, they evaluate evidence presented by the prosecutor and decide if it is sufficient to indict (bring a criminal charge against) a person or corporation.  The grand jury does not decide the guilt or innocence of the accused.
