Ukulele Chords Dm Explained
Following the major and minor scale formula, we can deduce from the root note onwards what the notes of the corresponding chord will be.
If our root note is D, which it is in this instance, then we can work onwards. Since we are looking for the minor triad, we will be seeking the minor third and the perfect 5th. In this example, the minor 3rd for D is F, with the perfect 5th coming in the form of A.
The more astute of you will have noticed that the only difference between a major triad and a minor triad is the difference between the third scale degree, major in the former and minor in the latter. So, for a major triad with a root note of D, we simply take that minor 3rd F and augment (sharpen) it by one semitone, so that it is now F#.
You can do this in reverse too, working with the major first: identify the 1st, 3rd, and 5th scale degrees in a D major scale which are D – F# – A; because the chord Dm is a minor triad, diminish (flatten) the 3rd scale degree a half step in accordance with the minor triad formula, which results in the notes D – F – A for the D minor chord.
