In musical terms, the third subdivision of the whole note
It represents one eighth of one whole note, which breaks it down to eight eighth notes per measure in common time
This means that in 4/4 or common time (having four beats to the measure and the quarter note being worth one beat, as is indicated by the time signature itself) a whole note is worth four beats, a half note
is worth two beats, and a quarter note
is worth one beat.
Because of its exact placement in and around the downbeat, eighth notes are commonly used for drumline exercises
. These exercises build exactness of timing, shape of attack
, and rhythmic consistancy. The normal exercise calls for eight eighth notes played by the right hand, immediately followed by eight eighth notes on the left hand and then repeated once. Usually began at a medium pace
and dynamic and then varied.
