Octave Shapes

Learn how to name every note all over the guitar fretboard by using Octave Shapes!

The Note Trainer App is very helpful with this lesson.

Does the note circle theoretically go forever in each direction? Or is there an “lowest” and “highest” octave in music theory? How are they rated to know the difference between the same notes on different octaves?

Jesse, my answer would be that it would be bounded by the range of human hearing range (typically 20-20000Hz). A piano’s range is 27.5-4186 Hz. A guitar around 80-1200 Hz

I don’t know enough about the physics of sound to talk about how the harmonics in the high range are created when you play notes on a guitar.

Theoretically, it is only bounded by the bounds of numeric calculation.
Practically, a decent visual of the limits would be a piano keyboard of 88 keys:
This equates to seven + octaves.

The last octave shape (6th string to 1st string same fret) is not one but two octaves apart. Do our ears need to know that or is it enough to recognise the common note?

Any reason why PMT does not show as In Progress in the Dashboard Journey entry ? :sunglasses:

Edit - scrub that its now showing. Satellite delay ?

Just started out on music theory, but you have answered a query I had, that the 1st and 6th strings are two octaves apart. I expect this would come up at some point in the course

Maybe in the ear training it might. I have since learned that theory wise they are there as a tool to help us locate the notes on the strings.
There are some shapes that crop up in lead and rhythm playing, so they are useful.

Thanks Dave @dave.pritchard101
I am only two months in with the guitar, started pmt and just had my first singing lesson. Will get around to ear training but I think I have enough on at present.
