Any note or phrase where the rhythmic emphasis (attack) or accent(s) falls on the downbeat(s) (beats, 1, 2, 3 and 4 in * time) of a measure, is considered non-syncopated.
Therefore, a note or phrase is syncopated when the attack or accent(s) falls on the 'offbeat'(anywhere other than the 'downbeat').
Bass Part - In this example syncopation is introduced.
Drum Part - In this example the bass drum plays a syncopated line.
A dot below or above the note indicates that it is to be played staccato (short detached note).
Bass Part - This syncopated line introduces a staccato note on beat '3'.
Drum Part - Upon repetition of this 2 bar phrase, the bass drum plays three eighth notes in a row.
