On a violin? On a piano?). On the same page of Beethoven piano sonata 32 in C, you find a Ab and a G#. According to the outlook above they are the 'same note' -- as I believed un= til I got a piano with alternate tunings, ie in addition to the usual equal=20 temperament there are now possible just-major and just-minor. Put the piano into just-major and the G# sounds good and the Ab not. Into just-minor and its the other way round. Now if you look at this (humongous!) list of possible notes http://www.kylegann.com/Octave.html you can see that G# ie augmented fifth is 772 cents ie 25/16 Ab ie minor sixth is 813 cents ie 8/5 IOW the augmented fifth and the minor sixth are separated by almost HALF a SEMITONE. [The tempered G#=3DAb is 800 a poor approximaion to both] What's my point? Civilization is digitization Digitization is information-loss This is true for music -- allowing for only 12 points in the =E2=88=9E spec= trum between frequency f and 2f makes music possible but also out of tune. The same is true of language -- words are an indirection, pictograms are (m= ore) direct. And ASCII... Hoo Boy! That's one hell of information loss! Thank God for unicode! ------- PS. And I should write not G# and Ab but G=E2=99=AF A=E2=99=AD
