Video: demonstration of the chromatic scales

The point of today's lesson is not to demonstrate how you can use the chromatic scale with 12 notes for your warm-up but how it is built. In other words, you will learn how this scale is put together. There are really 2 systems for this scale (I personally like the 2nd one better).

If you know how to build chromatic scales, you are not very far from building chromatic intervals, and consequently, the colorful seventh-chords.
