Sometimes a song does not begin on the first beat of a measure. Any notes which come before the first full measure are lead-in notes (or pick-up notes). When we use lead-in notes, the last measure is incomplete.
The notes in the lead-in and the notes in the last measure add up to one full measure. When you are playing chords, do not strum until the start of the first full measure, after the lead-in notes.
