[78-L] 7What key is that in?

[Malcolm Rockwell]

Thanks for the interesting reply and observations.
My "chest resonance" theory actually points up that there is no such 
thing as "perfect pitch." It's actually all relative pitch. You are 
relating all secondary pitches to one you are familiar with, thus 
"relative pitch."
I agree with your "untrained ear" observation. It is mine too.
Also with discovering a great piano tuner. I have found a few in my 
time. Unfortunately they get old and die and are mostly replaced with 
amateurs with electronic gizmos that do all the underlying work for 
them. Badly.
As to different keys on the piano sounding out of tune to C or A. If you 
do not temper the tuning that Gb will be all over the place, and other 
keys wiill be "colored" also. Personality of a key comes mostly from 
fingerings and hand positions as well as the specific training the 
pianist has, but I didn't mention that. It's why Ab and Eb are great for 
ragtime, C and G are great for boogie-woogie.  Seems though that E an A 
are only used for blues because the guitarists use a standard E or A 
tuning. There's also the differences in perceived harmonics due to 
different techniques and materials that go into the manufacture of a piano.
One of my favorite pieces for piano is "Rhapsody In Blue" mostly because 
it uses almost all the key sigs there are for the same theme (the first 
one, as expressed in the opening bars, played by a clarinet in concert. 
I haven't looked to see which keys are not used but the piece really 
gives a piano player a workout on a lot of levels!
Thanks again for an intriguing read.

Most professional musicians with good "ears" do not fall into that trap. Note, please that I said "most" and "good" There are plenty of professional musicians out there who, unfortunately have merde in their ears and can't tell the difference.  This aspect of the human ear was explained to me in the sixties by a well established and respected audio equipment designer and manufacturer of excellent audio components. It immediately struck a chord with me and clarified some of the problems I'd been having with certain (some highly respected) string bass and tuba players who tended to play flat much (if not all) of the time. It also explains why so many lesser lead trumpet and alto sax players from the big band era played sharp. some would actually claim

Piano tuning at one time was a generally pleasant, self-employed profession. It attracted many clods who would give you this and that about stretching this and that and all sorts of BS. When they were done, the piano was still out of tune.

The fellow who came did an absolutely superb tuning and fairly quickly. When I inquired that he must be a musician he claimed to know nothing about music. But he obviously had been well trained and knew what to do and how to temper the tuning which is the secret.  He was no longer available for subsequent tunings so I called upon musician friends/colleagues who'd become tuners. The results were always less than stellar and mostly unsatisfying. I ended up buying a tuning hammer, felts, wedges, etc. and tuned it myself. Without going through the typical song and dance that many tuners including my friends employed I was able to tune it to my satisfaction-far better than all the tuners that followed my initial free tuning. My point is that there's a lot of mystique and nonsense that goes along with tuning and I feel that you may hav

> Tempered tuning was invented  so that keyboards could play in any key and modulate from one key to any other without problems. Before the advent of tempered tuning that was not possible for keyboards. Unlike keyboards and fretted instruments orchestras do not play in tempered tuning. Their tuning is called just intonation. As a result, keyboards, are actually out of tune with orchestral tuning  (just intonation) but the ear adjusts. Orchestral players automatically adjust their playing as necessary so that it all (usually) works out.

> Tempered tuning involves the adjustment of certain intervals so that all notes are equi-distant from each other unlike orchestral tuning.  In tempered tuning the intervals of thirds, fourths and fifths are adjusted accordingly. Fourths are stretched slightly and fifths are com[pressed slightly. In orchestral tuning fourths and fifths are called perfect fourths and fifths. There is no vibration resulting from the two notes of a fourth or fifth when they are tuned as a  "perfect" interval. In tempered tuning the tuner counts the vibrations resulting from the compressed or stretched intervals  and sets the strings accordingly or he does it by ear from experience. Similar adjustments are made to the interval of a third. When done properly, the keyboard is in tempered tuning, all notes are equi-distant from one another and can modulate from any key to any other.

> Tempered tuning has nothing to do with, as you stated "a G flat major scale will sound  almost as good as a C major scale when played" other than that they will each sound correct if the tuning is correct. There is no (NO!) difference in the sound of similar scales, keys or whatever in tempered tuning,\. The only difference to be heard is the difference in register (higher or lower) which the untrained ear may interpret incorrectly. In my early career as a professional I too believed there was a difference until the illogic of it was explained to me by musicians more experienced and aware.
