Yes but many other guitarists for the last 50 years used tuning machines to tune their guitars which means the strings are in ET rather than in pure,to each other. Is it 90% of all guitar music you hear recorded and performed coming from instruments tuned by machine, with exceptions being in classical?

Ok maybe I am using the wrong term. But what are the holes for in the bassoon? To give a pitch? Why is that not called a fixed pitch? Because the player can "bend" it? What term should be used then, to distinguish the pre determined pitch of the bassoon and the variable pitch of the trombone? Also I would like to know how your bassoon was actually made. Did the craftsperson sit at a bench and file the holes so that the pitch agreed with an electronic tuning machine? If so then your bassoon is in ET. Or if not then what pitches were designed will tell the anti ET trio what to say about anti ET. > And what does the > width of the octave have to do with the necessity of ET? It means that every note in the octave can be expressed as powers of 2. It can be seen on a monochord. Divide the string in half and you have the octave. But how to divide the string into 12 equal parts within that octave? ET is expressed by the mathematical concept of 2^(1/12), or the twelfth root of two which means 12 notes are of equal proportion within the octave or a proportion of two to one. There are other ways of expressing the proportion of the notes again illustrated by the monochord. The 2/1 width of the octave and the "necessity of ET" is a bit of a stretch but consider what is available in reality. What system is 1/1? So what is the next system,,,,2/1? It turns out 2/1 is the octave of music. What about 3/1? What about 5/1? What about 10/1? 10/1 is our counting and number system. Every number of our system can be expressed as a power of 10. Every musical note can be expressed as a power of 2. 2^(1/12) expresses C#. 2^(2/12) signifies D. > > ric again: > The only "norm" I know in music among players is to match > pitch and "make pleasing harmonies".

But the proximity to ET since 1800 has been closer to "the norm" than certain publications and posts here endeavor to say otherwise. > In fact, what is the > "litmus test" > for ET? It is what my teacher told me, and what another master tuner told me, and another master tuner told me. At any PTG convention you can get an idea of what tuning is a "litmus test" of ET.

Why do you not want to tune ET? Do you do this by ear or by machine? Is it the same every time. How did you learn this? When you play are you constantly reassured this "offset" does indeed sound better than ET. Can you perform and demonstrate this? If so would you be willing to play blind fold on a piano you tuned and a piano I tuned for an audience who would "judge"? I am not gung ho on 3rds. Below F3 they can be ambiguous esp in and around the break. Maybe your temperament might test out as ET to me, but yet a machine might show "deviations". Are you > saying that for > the last 200 years, pianos have been tuned to within a cent > of ET? Using > what methods? Within a cent, yes probably among the most skilled and those attempting ET the best they could of the times. You have to realize ET is an evolutionary process that went hand in hand with the evolution of the piano. There are too many unknowns to say ET 200 years ago was within one cent. Cents weren't even known until 1870. How do we know there were not scaling problems that prevented the tuning of any temperament with in one cent? You asked what methods, I have the words of James Broadwood himself how to tune ET in 1811. Of course there will be those who argue, "well it could not be within one cent" Well so what? What tuning today is within one cent? I am sure you can take any machine and test any tuning and find one or two or three notes more than "one cent off". >You > may KNOW the > truth of ET being the norm for the last 2 centuries, but I'm > afraid reality > shows us otherwise. Well that is nothing to fear. Go and do the research and share it. Especially if you are literate in French, German and Italian. There are many works on ET from the mid 1700's to 1850 that need to be dug up. >From 1850 there are many texts available in university libraries and microfilm of magazines of the 19th century.

We all miss in every tuning one or two or three or more notes by more than a cent. Does this mean we don't tune ET? That is not the point. The point is we get as close as we can, just like the performer wants to get as close to the perfect performance. That we piano tuners can be measured to "one cent" is part of the turf of 21st century tuning. ----ric moody
