Playing Dominant b9 (Flat 9) Ukulele Chords

Video Transcript

"Now we'll talk about the upper tension, a flat 9. Now, again, keep in mind that 9, 11, and 13 refer to 2, 4, and 6 of a major scale. But we use 9, 11, and 13, usually, when there's a 7 present in the chord. And, if you just said a Dominant 9 chord, it implies it's a 7 chord with a 9. So, here, we're going to use a Dominant 7 flat 9 chord, or Dominant Flat 9 chord. So, let's start with the C chord again. Now, we've got two C's in here, we're going to lower this one a half step to 7, a half step to flat 7, giving you a C dominant chord. Now the 5, we mentioned, is optional. So, we'll take the 5 up a whole step to 6, up a whole step to 7, up a half step to the root, up a whole step to 9 which is the same as 2. We want a flat 9 so we're going to back that off by a half step, lowering it to a flat 9, giving us a dominant flat 9 chord."
