hi all
sorry if this looks numb and fool
but l do really want to know the reason why music in all of its form has only those seven notes C D E F G A B and no more ( i know about sharp and flats )
but i want to know how they conclud that these sevens are enough to cover all neccessary sounds?and they are musical frequency?
and something else about guitar why they choose strings as E B G D A E an not something else like G D E A B E B or anything else
thanks

about guitar tuning:
i think people searched with intervals they need to be able to play as many chords as possible as easy as possible. so they found out the which intervals and notes they needed.

i also thought about the first question but can´t find any answers

the 12 notes used are all you need, and I doubt your ever going to hear an actual musical note that isn't one of those 12. They use A-G plus #'s and b's because of how they decided to set out the harpsicord, then transfered it to piano/keyboard. It allows for simplicity.

The guitar is tuned the way it is for balance and simplicity, as daniel_s said. The B string is a different interval for the sake of balance and keeping chords/scales easy to play.

The reason there's 12 notes is because that's how music was developed in the West. Go to Asia and India and they have much larger scales with demi-semi tones etc (which became popular in the West in the late sixties when people egan using sitars and the like).
And your question about tuning, well there are many different open tunnings, but they apply to specifc keys (for example, open G tuning), which helps the player to play a certain type of song easily (especially when playing slide guitar). But for general purposes, the standard tuning is probably the easiest for scale patterns and chord shapes.

but you won´t hear any music with other notes because every musician knows ony those.
i think it would have been also possible to have for example10 or15 notes in one octave.
ok it wouldn´t be called octave then but i can´t see any reason not to have that

thanks for answrs
about tuning now it makes more sense
but for my first question hm.... still i dont get it anyway why?

the notes are that way and always have been. it spans far enough to cover everything because there are different keys, flats and sharps, and different things you can do to alter sound. i just get into music theory myself not to long ago and what you need to realize is this. a guitar is a guitar and it makes music. so even if you knew nothing about notes, theory, scales, any of that, you could still play music. all of the notes are HIGHLY reccomended to learn but not nessicary. and the strings are called that because those are the notes they make when played open. also if you look, the high e and the low e make the exact same notes! this is important to learn, exact, note for note, they are the same. open, both are E, 1st fret both are F, i can keep going on. i realy hope this helped, any questions send me an e-mail at BATBOY420494@AOL.COM

It would still be called an octave, as the ratio between the two notes would stay the same, just all the notes between would be at different places.

The reason why 12 tones are used, is because whilst using 12 tones, it is the closest we can get to having 12 pitches which relate based on octaves always being 2:1, fifths being 3:2, and major thirds being 5:4. Our octaves are exactly 2:1, always. Our fifths are very close to 3:2, but are not perfect. Our thirds are more out of tune than our fifths, but are still fairly close. 12 tones allows for, whilst using any given note, to have constant defined frequencies for each pitch, the most consonant sounds possible without using a ridiculously large number of tones.

The reason why these notes are consonant has to do with physics, and I will not type that out as it doesn't really relate to this discussion.

thanks so far
so if i get you correctly you mean in breif that these seven notes and their relative division and multiples are some kind of special frequency that sounds beautiful to brain and the others frequency are not yup?
so can you tell what is so special about these frequency ?

There are 11 notes formally used in Western Music (not including the octave). The sharps and flats are included. However the other micro-tones are informally used with every bend or vibrato, and by everybody who plays a fretless instrument or trombone or similar instrument. Pianists don't even think about those "grace" notes. Reed instrumentalists can get some microtones by changing their mouth position and partially opening certain valves.

The sound waves of a high E are proportionally the same as a low E so they sound similar, thus not requiring additional "names". It's the frequency that changes, allowing you to distinguish the two. The faster the frequency, the higher the pitch.

Alternate tunings are often used because they can make fingering (both right and left hands) a lot more simple (or more difficult) and to extend the range of the instrument. Standard tuning is used because it is generally the most versatile tuning. It allows you to reach three octaves and all the notes in between in one position.

I can't tell you why the brain likes these notes but it must have something to do with our ability to process information. Our brain naturally tries to "standardize" input. If not it would be like listening to an infinite number of tones and trying to make sense of it. I guess that's what brought down the Tower of Babel.

Like someone already said, the tones are the way they are because western people thought that in 12tet there was the most consonance. There are many other temperament systems. It has nothing to do with humans liking 12tet more. I mean, we all probably do since we're used to it, but humans have no natural disposition.

Edit: to the person above me: there are 12 semitones not counting the octave
