In this lesson we are going to add bass chords to the three single bass notes that we learned in the previous lesson. If you recall, you find the C button by finding that little rhinestone in the middle of the keyboard and put your middle finger on there. If we line up our index finger and fourth finger with the middle finger in that line, we will have C, F and G. If we move our fingers just down, and by down I mean towards our palm, towards the bottom of the accordion, we now have major chords, and they line up with the single bass notes that we were just playing. This is a single C note. Now I move finger just down I have a C major chord. A chord is three or more notes played simultaneously. On an accordion you only have to press one button to do that. If I find my G button and move the finger just straight down the diagonal row, I will have a G major chord. Same with F, F chord. Again this is the basic of many of folk and many of rock songs. This is a called a one-four-five pattern. In rock music with rock musician, you will hear this a lot. This C in this case is one. The F is four notes away from C. So that is the four. The G is five notes away alphabetically from C, so that is five. One, four, five, one. Now if we add the chords, simply swing your index finger around under the middle finger to get that c chord. Now we can move both fingers up for the G chord, back down to the C. Down to the F. Here is a trick, skip the C, go to the G, play the C again. This is the basis of many a song, and now you can play in any key because anywhere you start can become one. You just go down one to four. Skip one, go up to five. Back to one. This is the beauty of the accordion and why it is a favorite folk instrument, and that is the basics of moving from bass notes to chords. In our next lesson, we are going to create the classic accordion umpah sound by moving three fingers at once on the bass side.
