The Diminished Chord
This is comprised of two minor thirds which are built on top of one another. A minor third has exactly three semitones, counting C to C# as ‘one’, C# to D as ‘two’, and D to D# or E flat as ‘three’. This is the first minor third.
From the E flat, we count up three semitones again which brings us to the note F# or G flat. This is the second minor 3rd, which is built on the E flat of the previous minor third.
Example of a Diminshed Chord: If we use note C as our root note, then
