text: You can also see that the quarter note is divided into 2 eighth notes (a crotchet is divided into 2 quavers) making each eighth note (quaver) worth half of a quarter note (each quaver is half of a crotchet), therefore we can say the duration of a Whole note (semibreve) is 4 quarter notes, the duration of a Half note (minim) is 2 quarter notes and the duration of an Eighth note (quaver) is 1/2 of a quarter note (crotchet).
