How To Play A Slur
A slur is when you combine two or more notes into the same bow stroke. When slurring two notes of the same value, use the same amount of bow for each note. Simply divide the bow stroke in half. Unless otherwise indicated, slur each note using a legato bowing.
A Slur is easily spotted as it looks like a smile or a frown under or on top of the notes. You want to play all of the notes connected by the smile or frown in a bow stroke.
