![]() ![]() By now you probably remember this is Dm, G, and C. By flattening this interval, it gives us a flat 7 because Bb is not in the C major scale.įor this explanation, let's look back at our ii V I progression in the key of C. We call the C-B 7th natural because it is naturally part of the C scale. ![]() If we add just one extension, so another 3rd interval, we get the 7th! By doing this we have a 4-note chord 1, 3, 5, and 7.Īs we know from the previous articles, the quality of the intervals (minor 3rds or major 3rds) is determined from the scale we use, for the 7th this determines whether it is a flat 7 (C-Bb, in Classical music theory, this is called a minor 7th interval) or a natural 7(C-B, also referred to as a major 7th interval in Classical music theory). We can even do this until we actually have a chord made up of all the notes in the C major scale (C-E-G-B-D-F-A-C)!Īs we know already, the tonic triad is made up of the tonic (1), 3rd, and 5th notes of the scale. If we want to take this tonic triad and add extensions to it, we would continue stacking thirds on top of it. For example in the key of C, the tonic triad is C major.Īs discussed in previous articles, this triad is created by stacking intervals of a 3rd taken from the scale, in this case the C-major scale. What are extensions? And what is the 7th?Ī triad, a chord with three notes, is derived from a scale. ![]()
