An eighth note triplet is a group of three evenly spaced notes played within 1 beat. Eighth note triplets are indicated by three eighth notes with the number 3 written either above or below the group.
Sometimes the triplet has a bracket or a curved line around the number 3. Eighth note triplets are played with a third of a beat each.
This example uses a constant stream of triplets on the chords played by the right hand.
This 12 Bar Blues combines triplets with the familiar left hand pattern. Notice the chord change in the second bar. This is referred to as a Quick IV (Four). This is because the F chord is built on the fourth note of the C major scale and is known as chord IV in the key of C. Chord numbers will be discussed further in lesson eighteen.
