So, this is a tremolo exercise that we're going to do. I'm going to put my metronome at beats per minute at sixty. And we're going to play eighth notes and then sixteenth notes and then move into triplet time. This is going to be clicking on two, three, four, one, two, three, four. And what I'm going to do is I'm going to always alternate pick. I'm just going to choose a D chord here and we're just going to use these strings. Now, to do the tremolo, I turn my pick just a little bit to a rounder edge just so I can get the roll off the strings. Three, four, one. So there are eighth notes for you. I'm moving to sixteenth notes here. Back to eighth notes, back to sixteenths. And when you just use two strings, it sounds even more aesthetic or more traditional to the sound.
