Frequently Asked Questions
What is a D7 chord?
A D7 chord is a dominant 7th chord built on the root note D. It is not the same as a major 7 or a minor 7. It has a special use as preceding the tonic chord in a cadence or at the end of a song.
By learning your dominant 7 chord shape and applying it to D, you can play this chord in any context.
What 3 notes make up a D7 chord?
Well, D7 technically has 4 notes. D F# A C. However, many times players will drop the 5th, just because it isn’t that important. If you just played D F# and C, it would still sound like and be considered a D7 chord.
This is really only done with chords with 4 notes, so you couldn’t apply this rule to triads.
