Video: demonstration of 3 types of major scale

If you know 5 different tetrachords, you can easily build 3 types of major scale - natural, harmonic and melodic. They are very useful to know for every organist because you can find them in many organ compositions. In this video, you will see my hands and the manuals of my church organ. My explanations are followed by actual demonstration of the scales so I hope after watching them, you can start practicing them as well.
