Learn Jazz Piano Chord Extensions in minutes

► Free Jazz Piano Crash Course: Extended jazz piano chords create a richer and more complex sound than triads and 7th chords and so they are used in jazz music to create more interesting harmonic progressions. This lesson provides an introduction to chord extensions, explaining what they are and where they come from. We will then look at some of the most common extensions for major, minor and dominant chords and review the most effective way to practise these extensions to be comfortable playing them in all 12 keys. What Are Chord Extensions & Where Do They Come From? Chord extensions occur when you extend a chord beyond the 7th note of the scale which takes you past the octave mark. There are three extensions, the 9th, the 11th and the 13th. If we continue to extend the chord past the 13th we get back to the root of the chord so the 13th is the highest chord extension that you need to learn. Be aware tha
