Piano Chords: Major 7ths, Minor 7ths & Dominant 7ths

In this piano tutorial, I talk about some very important piano chords, 7th chords! I also show you a quick and easy method to construct ANY seventh chord in ANY key.

Triads are chords made of up 3 notes, 7th chords are made up of 4 notes. Therefore we just need to add one extra note to a triad in order to construct a 7th chord.

The reason it is called a 7th chord is because we are adding the seventh note from the scale to the chord.

To construct a major 7th, play a major triad and add the 7th. To construct a minor 7th, play a minor triad and add the flattened 7th. To construct a dominant 7th, play a major triad and add the flattened 7th.

You can think of a major 7th as a '3-2-3' chord, a minor 7th as a '2-3-2' chord and a dominant 7th as a '3-2-2' chord. Use this trick to help work out these chords in any key.
