# Topic: Simple question about written octaves

1. ## Simple question about written octaves

Maybe not notation per se, but something that's confusing me. I'm going through a book and it has the names of the notes written like - g' a' b' c" d" e" - etc. I think however many ' marks there are designates the octave you're in, but I'm confused about it a bit.

This book is showing middle C as c', but I was thinking middle C would be c without the ' mark. I'm not sure about the bass clef since I don't see anything for it.

Middle C is C4, and apparently here it's shown as c'. I was thinking that the ' mark meant that it is one octave above middle C. So I think it'd work like this:

C0 - C?
C1 - C?
C2 - C?
C3 - C
C4 - C'
C5 - C"
C6 - C"'
C7 - C""
etc

So how do you designate below C3?

It's probably not c', it's probably c1.

Traditional octave registers are as follows:

Middle C to the B above is c1 - b1.
The octave above that is c2 - b2.
Ect...
The octave below Middle C is simply c - b (lower case letters are imperative in this instance).
Go another octave below that and it's C - B (upper case letters are imperative here as well).
Another octave below that is CC - BB.
and Below that are simply the notes AAA and BBB.

Stumbled across this by accident.

This is quite confusing to me. The way I learned it, the very last A on the piano is A0. Then, the lowest C is C1. In this system, Middle C is C4. Does this system have a name? I believe it is more technical than the others, but then again, I don't know how the other systems work.

Further confusion for you.

In midi, middle C (c') is C3 and is designated as note 60
In midi, note 0 is C-2.
There are of course 128 notes in midi ( 0 to 127)

The C4 version is rather new. I'm not sure what it's called. They've been using the others for decades, if not centuries.
