The famous sweep picking technique involves picking the strings in a fluid motion as if they were being literally swept. In the demonstration provided by instructor Sarache, first the regular picking technique is shown followed by the sweep picking. This is a relatively difficult technique to conduct as it does require a significant amount of control with the playing hand. Make sure that you practice this with scales and first conduct it slowly prior to bringing up the tempo.
Here we have included the scale of D Major so that you can practice the technique along with the scale itself. Start off picking the D Major scale with a normal finger picking technique, and then try to apply the sweep picking once you are comfortable with it.
