I am having a problem undersrtanding inversions of a basic idea. I understand it the steps between each but I’ve tried to follow some examples and can’t seem to get what the tutor says the same.
When inverting a basic idea, there are a few things that make it work:
- Make sure you keep the same rhythm. This makes it feel like the original idea.
- Make sure you keep the relative shape. If your original basic idea has an interval that goes up a 3rd, you generally want to keep that interval as close as possible going down.
- Make sure the melody and the underlying harmony work together.
The last one, is what makes the inversion still sound tonal.
This inversion meets all the criteria, but the range from top to bottom feels a little too expansive.
This one feels better, matches the harmony, and keeps the same intervals and rhythm.
Remember, that you can invert around any note, diatonically and chromatically. I would practice it, and see what works and what doesn’t.
That C to Db gets me. Co’s Db and C# are the same. So we count C to D to Db making minor 2nd. counting forwards then going backwards? Or is it C to C# to Db counting minor 2nd?
Effectively yes. For instance, the note C and C# together is called an augemented unison, but it is considered 1 step. C to Db on the other hand would be considered a minor 2nd, because the notes are not actually the same letter note.
When inverting, you have to choose which note to invert around, so in the case, I inverted on the G. That basically means to pivot everything on that note. Inversion is take much further in serial writing, where you invert more literally, and you can choose to invert around any note. Even a note that is not part of the basic idea.
For instance, if you were to invert this idea on the F#, the first note would be F not G, because you are pivoting everything based on the distance to that F#. G is a half-step above F#, and so the new first note would be a half-step below.
when counting intervals for inversions do we count 1 on the note we are counting from or from the next space or line.
I notice the first note is not inverted but the notes following, is this correct? Thanks
