Here we have a pattern in the style of Joao Bosco. 
Joao Bosco is a very important name in the Brasilian 
musical scene. He became famous by his special 
"ginga" (jin-gah) on right hand patterns/ Notice again 
the use of hi and low voices in the chord changes.

You can also play "variation#2" with an 8th note 
syncopation on the first beat (Figure 2).

Musical example (Figure 3): In this example, you can 
practice the pattern with and without the first beat 
syncopation.
