Answer:
In music, a whole note (American) or semibreve (British) is a note represented by a hollow oval note head, like a half note (or minim), and no note stem . Its length is typically equal to four beats in 4/4 time. Most other notes are fractions of the whole note; half notes are played for one half the duration of the whole note, quarter notes (or crotchets) are each played for one quarter the duration, etc. A whole note lasts half as long as a double whole note (or breve).
