Can someone tell me why on pianos B and C/ E and F are only a half step apart? and why they don't use blacks keys to represent that?
Because there is no note between B and C, but white keys are all the notes in the key of C major, and since B and C are both in the key of C major, they're still white.

So your saying that if C was a black key then c# would have to be a white key and then that wouldn't work? So it was built around C major and that's why there are no sharps or flats in there because the (2212221) 1's happen between bc/ef
Why is there no note between b and c? Is C just B# sharp but they call it C?
Well the notes are based off their frequencies, and there is no note between B and C. C and B# are "enharmonic", meaning same note, different names. It depends on your key.

If you are in the key of Bb Major, a C is a C. But if you were in, say, C# Major, you'd have a B#, you wouldn't call it C because C isn't in the key of C#.

Oh ok, I guess that makes sense, I'm kinda new at this. Thank you
Its because the white keys are based on the major scale, and the points with no black keys between are the 2 half step intervals in that scale.

If I remember right, some Greek chap (Pythagoras maybe?) started off by notating the natural notes (A B C D E F G), then people later noticed that you could have the same relationship between notes, but start from another note, hence altered (sharp/flat) notes to get scales like C minor and A major.

PS, C is enharmonic to B#, not B## (typo in your post?).

Take a look at a keyboard (I posted a picture at the bottom). Find a C, and play seven white keys going up from that note. The notes you are playing are C D E F G A B and then back to C. This is a C major scale, consisting of W W H W W W H (w=whole step, h=half step). That is the formula for a major scale. The reason I gave you the C major scale instead of the D major scale or F major or something, is because C major is the only major scale that uses no sharps or flats.

Now that you know this, take a look at a guitar, for now we'll look at the sixth string. The open string is an E, as well as the twelfth fret. Knowing that, there are 12 notes in between, (E, F, F#/Gb, G, A#/Bb, B, C, C#/Db, D, D#/Eb) going from the open string to the 11th fret, after which it repeats. Now let's take an E major scale. It has the same intervals, or formula, as the C major scale (because they're both major scales) but it starts on a different note. The notes are E F# G# A B C# D#, and I posted an image of it at the bottom.

Does that make a bit more sense?

Yep, it was Pythagoras.

Oh I know the major scale intervales octave oct 8 natural notes C D E F G A B C
12 notes all to gether and how it relates to guitar, 12 fret 1 octav higher. 24 fret on low E equals open high E 2 octaves. I just didn't know why it was based on a major scale i just thought it was wierd that it wasn't something like WWWWWWW rather than WWHWWWH

A lot of people argue that it shouldn't have been based on the major scale. Check out http://en.wikipedia.org/wiki/Janko_keyboard

Lizst and Arthur Rubinstein (both world class piano virtuosos) agreed that it was a much better layout but it never caught on because the old layout was so well established.

Wow that is very interesting, I was wonder why the piano is layed out how it is and I guess the answer is just "because." That's a pretty cool looking piano too bad it never caught on, thanks.

6-6 keyboards just make more sense. A regular 7-5 is like having a dozen different instruments, with a different fingering pattern for every key. The time spent learning all of those patterns could be better applied.

I think the bigger problem is that anything over a 9th is really uncomfortable for anyone who isn't a mutant

I'm not sure if that is worse than the lack of uniformity, but I definitely agree octaves are spaced too widely on a typical 7-5 keyboard - often on the order of 6.25 inches. A Jankó could be comfortably spaced at 5 inches, which would allow a single hand to cover an 11th in about the same span as a 9th on a 7-5.

Why would a Greek chap have used the Latin alphabet to name notes?

I can just barely reach an 11th but it's uncomfortable.
