So far as I understand it, Western music uses a 12-note chromatic scale from octave to octave, and modern instruments use even temperament.
Other cultures have smaller intervals, meaning a different idea of musical scale, and just intonation means in some keys the note blow a D is a C#, sometimes it's a Db- and in fact the two aren't (in theory) the same pitch.
However, in practice...
On a keyboard, to play (for example) a C# of a given octave, there is just one key for that note.
--- > One.
Is there a naming system which uses just one name for any note (pitch) ? If so, what's it called ?
I'm thinking of something that has just 12 note names and something to indicate an octave.
And lastly (optional): If not, why not? this isn't really me provoking response .. it might be that there's a very practical reason why there isn't such a language, but I'd like to cast aside "because we've always done it that way" as a reason. Unless it iactually is the only reason.
