Scott Giambusso: Scott Giambusso, your bass doctor here. Today we are going to discuss diatonic tense. I am going to use the key of F. Now, you know a major scale, an F major scale, if I play it on one string with my first finger playing all the roots, its going to look like that. Now, what I am going to do to play a tenth, its a harmony, tenth is a third an octave above the third. So, if I go one, two, three, four, five, six, seven, one, I call one the octave eighth, eight, nine, ten and so there is my tenth. We have the beginnings of harmony here. Now, the tenth lower. So, what we are going to do is we are basically playing the F scale, starting on the third note. Its a mode, its actually the Phrygian mode of the F major scale, its called the A Phrygian. So, what we are going to do is play the F and the A, then we are going to go up a whole step to the G and play half step above the A, the B flat that creates a G minor chord or a dyad anyway, it implies G minor. The third note of the scale is theres your A and we play a C on top and however you want to do it, you could it with one hand, or one finger, two fingers. These fingers seem to work the best for me. The fourth note of the scale, the B flat, it says its a major third. Basically its either major third or minor third. So, I want to begin again. The one chord is a major third, the two and three are both minor thirds or minor tens, the four and the five are major, the six and the seven are minor and the eight is of course major, so it sounds like this. You can do it in different keys, you can do in G, Ill do it backwards in G. Heres five, four, three, two, one. I always try to sing my pitches, it helps to sing, I can tell you. When you get that down and you do every other one, lets go back to F; F, A, G, B, flat A, C, B, flat D, C, E, D, F, E, G minor, F and you get some facility moving through the chord structure and it helps you here.
