In this session, we will use an existing scale that we know, C Major, and derive other scales from the tone group. There are 7 tones in a Major scale, therefore, we will have 7 modes. Each tone of the scale can be a ‘starting point’.
As previously discussed, modes are tone groups, aka scales. They are scales with special names. Scales which produce specific types of sonic ‘impressions’.
One way to understand/play modes is to use a scale that we know, such as the C Major scale. Then, play the scale using the different tones in the scale as ‘starting points’. This is called derivative – we are deriving scales from a scale.
The way we did it before was to use a scale, such as the pentatonic, and treat it as a shell by adding tones to fill in the ‘gaps’.
Even another is to use formulas. We can modify a Major scale to create modes and their formulas [parallel]. We can also have a mode, created by whatever means [synthetic, etc.] and understand it by how it differs from its own Major scale. This will also produce a formula.
Finally, we can also divide an octave any way which we choose → create our own modes. If modes we create aren’t previously named modes, we typically call them synthetic modes [scales we synthesized].
