To expand from a five-finger exercise, we're going to try a one octave c major scale, and a one octave c major arpeggio. With our right hand, let's just do what we call a cluster over middle C, D, and E with fingers 1, 2, and 3. Remember involve your breathing in this. This transfer or thumb all the way up to F and we're going to play all five fingers at once. Now we're going to do this back and forth. This is informing you of what is the order, all the fingers, as we play a one octave c major scale. Let's try this node by node, 1, 2, 3. Our thump goes under on the F. Let's try that same thing with our left hand. We'll do the cluster with all five fingers. Our pinky or fifth fingers on the c, one octave below middle C. Then we're going to position our third finger over the A, second finger over B, and first finger over the middle C. Just those three nodes. Now let's go back and forth with a two positions. Five finger cluster, three-finger cluster. Once again, this is giving you the information of the order of the independent fingers as you play the C major scale. Third finger goes over. First finger goes down into G. Once you're familiar with this, you can try the C major scale on one octave with both hands. Now you know how to play a C major scale. Let's try the same thing with a one octave arpeggio. With our first finger, we go on middle C. Our second finger goes over E. Our third finger goes over G. Our fifth finger goes over the C, one octave higher. This is for our right hand. Notice my hand is not rigid, my fingers are relaxed and I'm allowing my arm to carry me from the C below to the upper C. On our left hand, fifth finger over the lower C. Third finger over the E. Second finger over G. First finger over the upper C. Again, let's try this. Once again, we want our hand to carry us forward and back. We're not going to keep our fingers rigid as we play this. This right now with both hands. Just like that, you're now familiar with a C major scale and a C major arpeggio for one octave. Next, I want us to think about the 1, 4, 5, 1 cadence or chord progression. This is a very popular chord progression. If you listen to songs like La Bamba or Lucy in the Sky or like a Rolling Stone, these are songs that definitely imply a 1, 4, 5, 1 progression. Let's travel through the C major scale with a triad. Triad meaning three nodes simultaneously over the C major scale. This way, we're familiar with all of the triads within the C major scale. This is 1, 2, 3, 4, 5, 6, 7, and back to the 1, one octave higher. The C major triad in root position can go into the first inversion, which means the lower note now goes one octave higher. Let's see how that sounds like and looks like. Now the Es at the bottom, the Gs and the middle, and Cs at the top. Let's travel over the C major scale this way. We'll try the same thing with second inversion over the C major triad, which now means that G is at the bottom, the C is in the middle, and the E is at the top. Try the same thing with your left hand. Root position. First inversion. Second inversion. Why do we want to be so familiar with every single position of the triads is because we want to avoid doing big leaps if we travel from the one to the four, to the five and back to the one. If we play the one here, the four here, the five, and back to the one, we're jumping from one place to the other end, the piano, and that could cause stress. There's a way of traveling from cord to cord without having to move that much. Check this out, 1, 4, 5, N1. Let me play that. As I play a single line base node on our left hand. We will get a complete different sound if we're trying that for the first inversion over the C major, and the same thing over the second inversion.
