A quarter note (American) or crotchet (British) is a note played for one quarter of the duration of a whole note (or semibreve). Some people will say that a crotchet is one beat, however, this is incorrect, as a beat is decided by what time signature the music is in. Quarter notes are notated with a filled-in oval note head and a straight, flagless stem. The stem usually points upwards if it is below the middle line of the stave or downwards if it is on or above the middle line. However, the stem direction may differentiate more than one part. The head of the note also reverses its orientation in relation to the stem. A related value is the quarter rest (or crotchet rest). It denotes a silence of the same duration as a quarter note. It typically appears as the symbol and occasionally as the older symbol .
