      through the wonders of Amazon I've managed to get a copy of "The Third Ear" by Joachim-Ernst Berendt. ( I lent my original version and as usual it never came back ) It's an amazing book and discusses the perception of the ear. It also discusses sound and it's influences. The foreword is written by Yehudi Menuhin.

      Here are some figures for you to contemplate.

      *The Day tone is the note of a day of 24 hours, or more precicely 23hrs, 56mins, 4secs or 86,164 seconds. Frequency = 1/Time….. therefore the day tone = 0.000,001,160,576hz..

      Octavised upwards by 24 octaves produces a note of 194.71Hz. (G)

      Octavising upwards another 40 octaves we reach a frequency of 427 billion Hz. Or 702 nanometers, the luminous orange/red worn by Sanyassins.

      If we pass through one more octave we reach the 66th octave and the precise resonance frequency of DNA.

      The Earth or Sun Tone can be calculated on the basis of the tropic year that lasts 365.2422 days, 525,948 minutes and 46 sec. Or 31,556,926 seconds.

      Octavised upwards by 32 octaves produces a frequency of 136.102Hz. This corresponds to the Indian Sa or Sadja note which the Indian master teaches his pupil as the pitch note and has not changed for thousands of years.

      Hans Cousto in Munich induced geraniums to bloom in winter by holding a tuning fork producing the sun tone near the flower pots for just a few minutes per day.

      The moon tone is the period between two equivalent lunar phases i.e. full moon to full moon and lasts 29days, 12hours, 44 mins, 2.8secs. or 2,551,442.8 secs. Transposed upwards by 30 octaves produces a note of 420.837Hz. (G#) In the Baroque era Mozart’s tuning fork vibrated at 421.6hz, Handels’ 422.5hz and Bach’s 415.5hz while concert pitch was 422hz in Berlin at mid-eighteenth century and 423hz at Paris in 1810. Only after 1820 did the rise in concert pitch get underway.*

      Here's an article on pitch and tuning from the Schiller Institute who have been campaigning for a universal drop in pitch.

      *A Brief History of Musical Tuning
      by Jonathan Tennenbaum
      Reprinted from FIDELIO Magazine,
      Volume I, No. 1, Winter 1991-92

      The first explicit reference to the tuning of middle C at 256 oscillations per second was probably made by a contemporary of J.S. Bach. It was at that time that precise technical methods developed making it possible to determine the exact pitch of a given note in cycles per second. The first person said to have accomplished this was Joseph Sauveur (1653-1716), called the father of musical acoustics. He measured the pitches of organ pipes and vibrating strings, and defined the ut'' (nowadays known as do'') of the musical scale at 256 cycles per second.

      J.S. Bach, as is well known, was an expert in organ construction and master of acoustics, and was in constant contact with instrument builders, scientists, and musicians all over Europe. So we can safely assume that he was familiar with Sauveur's work. In Beethoven's time, the leading acoustician was Ernst Chladni (1756-1827), whose textbook on the theory of music explicitly defined C=256 as the scientific tuning.Up through the middle of the present century, C=256 was widely recognized as the standard scientific'' or physical'' pitch (see Figures 13 and 14).

      In fact, A=440 has never been the international standard pitch, and the first international conference to impose A=440, which failed, was organized by Nazi Propaganda Minister Joseph Goebbels in 1939. Throughout the seventeeth, eighteenth, and nineteenth centuries, and in fact into the 1940s, all standard U.S. and European text books on physics, sound, and music took as a given the physical pitch'' or scientific pitch'' of C=256, including Helmholtz's own texts themselves. Figures 13 and 14 show pages from two standard modern American textbooks, a 1931 standard phonetics text, and the official 1944 physics manual of the U.S. War Department, which begin with the standard definition of musical pitch as C=256.[1]

      Regarding composers, all ``early music'' scholars agree that Mozart tuned at precisely at C=256, as his A was in the range of A=427-430. Christopher Hogwood, Roger Norrington, and dozens of other directors of orginal-instrument orchestras' established the practice during the 1980's of recording all Mozart works at precisely A=430, as well as most of Beethoven's symphonies and piano concertos. Hogwood, Norrington, and others have stated in dozens of interviews and record jackets, the pragmatic reason: German instruments of the period 1780-1827, and even replicas of those instruments, can only be tuned at A=430.

      The demand by Czar Alexander, at the 1815 Congress of Vienna, for a ``brighter'' sound, began the demand for a higher pitch from all the crowned heads of Europe. While Cclassical musicians resisted, the Romantic school, led by Friedrich Liszt and his son-in law Richard Wagner, championed the higher pitch during the 1830's and 1840's. Wagner even had the bassoon and many other instruments redesigned so as to be able to play only at A=440 and above. By 1850, chaos reigned, with major European theatres at pitches varying from A=420 to A=460, and even higher at Venice.

      In the late 1850's, the French government, under the influence of a committee of composers led by bel canto proponent Giacomo Rossini, called for the first standardization of the pitch in modern times. France consequently passed a law in 1859 establishing A at 435, the lowest of the ranges of pitches (from A=434 to A=456) then in common use in France, and the highest possible pitch at which the soprano register shifts may be maintained close to their disposition at C=256. It was this French A to which Verdi later referred, in objecting to higher tunings then prevalent in Italy, under which circumstance ``we call A in Rome, what is B-flat in Paris.''

      Following Verdi's 1884 efforts to insitutitionalize A=432 in Italy, a British-dominated conference in Vienna in 1885 ruled that no such pitch could be standardized. The French, the New York Metropolitan Opera, and many theatres in Europe and the U.S., continued to maintain their A at 432-435, until World War II.

      The first effort to institutionalize A=440 in fact was a conference organized by Joseph Goebbels in 1939, who had standardized A=440 as the official German pitch. Professor Robert Dussaut of the National Conservatory of Paris told the French press that: ``By September 1938, the Accoustic Committee of Radio Berlin requested the British Standard Association to organize a congress in London to adopt internationally the German Radio tuning of 440 periods. This congress did in fact occur in London, a very short time before the war, in May-June 1939. No French composer was invited. The decision to raise the pitch was thus taken without consulting French musicians, and against their will.'' The Anglo-Nazi agreement, given the outbreak of war, did not last, so that still A=440 did not stick as a standard pitch.

      A second congress in London of the International Standardizing Organization met in October 1953, to again attempt to impose A=440 internationally. This conference passed such a resolution; again no Continental musicians who opposed the rise in pitch were invited, and the resolution was widely ignored. Professor Dussaut of the Paris Conservatory wrote that British instrument makers catering to the U.S. jazz trade, which played at A=440 and above, had demanded the higher pitch, ``and it is shocking to me that our orchestra members and singers should thus be dependent upon jazz players.'' A referendum by Professor Dussaut of 23,000 French musicians voted overwhelmingly for A=432.

      As recently as 1971, the European Community passed a recommendation calling for the still non-existent international pitch standard. The action was reported in The Pitch Game,'' Time magazine, Aug. 9, 1971. The article states that A=440, this supposedly international standard, is widely ignored.'' Lower tuning is common, including in Moscow, Time reported, where orchestras revel in a plushy, warm tone achieved by a larynx-relaxing A=435 cycles,'' and at a performance in London a few years ago,'' British church organs were still tuned a half-tone lower, about A=425, than the visiting Vienna Philharmonic, at A=450.

      Currently I am mastering plastic didgeridoo I also made from fat plastic 2 meters long

      I once made a didge out of two pieces of plastic downpipe where one slid within the other so you could tune it. In recording the didge with a band it's often hard to get the damn things in tune but the variable length tuneable didge seemed to work.

      here's a track I recorded where the didge was around 4 tones lower than the track - we slowed the multitrack recorder down to meet it then bought it all back up to speed. It took a lot of breath to play it that slow. 😉

      the artist is Troy Cassar Daley.

      looks like there's some serious programming going on there and it sure is appealing.

      There's $2 million waiting for the person to come up with a vehicle that will travel a specific distance (over 100 mile) without a driver. Not only must the car drive itself, i.e steer, change gear, etc. but it cannot be hooked up by remote, in other words the car has to think for itself all the way through the course.

      Interesting person Mike - he's pro Thatcher, pro Monarchy, pro Nuclear Power and pro GM food yet is idolised by the environmental left. Go figure.

      I do like his idea of a living planet, I'd even take it further to a living universe where everything has a life of some kind and moves to sustain it.

      Politics...religion!! I feel that they should be completely shut out of here...I have rarely seen those threads go anywhere but finnally into the toilet. I deleted a thread once. ( I could get rid of it cause I was a moderator at the time) Of course there was a great cry about it and I expected that, but like you I thought the thread had turned to poisen and it needed to be killed and removed so that all wouldn't stumble into the sh*t.

      that is purely your opinion. I have a different opinion which I am entitled to. I resent you trying to force your opinion onto me by deleting threads, thank you very much. 😡

      I might add you don't even have the courtesy to indicate where you come from in your profile.

    • RE: Politics Forum....

      come on - the original corner bar at sketchup was full of political rants. remember Gary?
      I think the politics forum is a good idea - if you don't like it - stay out of it!

      I've learnt a lot about other people's and other country's attitudes to all sorts of social and political situations. For the better IMHO.

      Yes - one of the mods is outspoken and forceful in his political attitudes - what gave me the shits was when someone here started a thread then abused him and me for taking part in it.

      At a musician's forum I frequent the political forum would out post the rest of the forums 5:1. That's the nature of forums.

    • RE: Some Art

      I'm not sure Rob - Red Bull approached the local art galleries when they setup the music academy in Melbourne and asked for artwork to decorate their academy. The artists were paid plus they were allowed to take the artwork back when the academy was finished and the building returned to it's original state ready for the developer to turn it into apartments.

      They are establishing this years academy in Toronto as we speak.

    • RE: Lumber (timber) sizes in the UK?

      same here James but tradesmen are really in demand. A developer near me on the Gold Coast is flying carpenters up from Melbourne, 2000klms away, housing them in hotels, flying them home every fortnight and paying well above award rates just to get his project completed on time.

      tradesmen are making 1500 - 2000 per week and all drive around in big SUVs and go fishing in the weekend in their big power boats. 😄

      So your 100mmx50mm is the same as our 2x4

      Joe - it's a direct conversion from metric to imperial. I have to work in both - fortunately sketchup doesn't care as you can type in 4" or 100mm and it makes the conversion automatically.

      Sorry - I have no idea how to access UK codes. 😄

    • RE: Lumber (timber) sizes in the UK?

      Joe - the brits use metric like us Aussies.

      In the US a 4" x 2" is in fact a 3 1/2" x 1 1/2" as 1/2" is lost in dressing the timber. It's called DAR (dressed all round) here.

      In metric a 4 x 2 would be 100mm x 50mm - after it's dressed all round it becomes a 90mm x 40mm (i.e losing 10mm (1/2") all round)
