Today we went through The Circle of Fifths and talked about it as both as an abstract theoretical concept and also as a working, practical set of musical tools. We talked about what it means, in a studio setting for example, to "change the key" for a singer that finds the key, or tonal center, the musicians are playing in to be too high or too low for his voice.
We also talked about the prototype major scale built on "C", and the the prototype minor scale built on "A", as being the old Ionian and Aolian modes from the older "modal' system.
We use just two of the basic modes in this new system, the Major and the Minor, and move, or "transpose", them, to any tonal center we choose. that's what we mean by "changing the key".
This is called the Diatonic System, and it is based on Tempered Tuning. [We'll be discussing these terms more as the course progresses]
Continue to work in your book through page 8.
On Wednesday we will continue with the Minor Scale, and the Harmonic Minor Scale.
