The stem is placed to the right of the notehead and extends upwards if the notehead lies below the middle line of the staff, and to the left of the notehead extending downwards if the notehead lies on or above the middle line of the staff, in instrumental notation. In vocal music, a middle-line notehead extends upward instead of downward. A related symbol is the eighth rest (or quaver rest), which denotes a silence for the same duration .

Musical note for this note is 440 Hz, although this varies in actual practice (see History of pitch standards). The note-naming convention specifies a letter, any accidentals, and an octave number. Each note is an integer number of half-steps away from concert A (A). Let this distance be denoted "n". If the note is above A, then "n" is positive; if it is below A, then "n" is negative. The frequency of the note ("f") (assuming equal temperament) is then: For example, one can find the frequency of C, the first C above A. There are 3 half-steps between A and C
