MUIC & ACOUTIC – MUIC THEORY & HARMONY CALCULATOR
Chord Extensions
A precise tool.
What is the Chord Extensions & How does it work?
Chord extensions are additional notes added to a basic triad (root, third, and fifth) to create more complex harmonic structures. These extensions include the seventh, ninth, eleventh, and thirteenth chords.
The formula for a major 7th chord is: (text{Root} – text{Third} – text{Fifth} – text{Seventh}). For example, in the key of C Major, the C Major 7th chord would be C – E – G – B.
Similarly, a major 9th chord adds the ninth note to the seventh chord: (text{Root} – text{Third} – text{Fifth} – text{Seventh} – text{Ninth}). Continuing with C Major, the C Major 9th chord would be C – E – G – B – D.
(text{Chord Extension} = text{Root} + (2^n))
n = number of half-steps from the root
