Which note does an orchestra tune to

There are two explanations: The first is that it is because the oboe has a stable pitch, and the other is that it is because, instead, the pitch is unstable. The two explanations are the complete opposites of one another.

Nearly all instruments have always been unstable in terms of pitch because of differences in heat, humidity, and the like. Typically, the instruments come with mechanisms that allow performers to tune them.

However, because of its structure, the oboe's pitch can only be changed by removing and inserting reeds. It is not possible to change how high-pitched the tones are the way that can be done by removing a clarinet's barrel or altering the tension of a violin's strings. When the first orchestras emerged in the late 17th century, they were mainly formed of string players. While the focus was on string instruments, oboists were sometimes used to strengthen the sound of the first and second violin section.

Longevity also has a lot to do with it: over time flutes, bassoons, French horns and clarinets drifted in and out of the orchestra; but oboes were nearly always written into orchestral scores. So they became the standard instrument for tuning. As soon as I give a sign, tuning is over, and everyone should remain quietly in his place. Other options included taking the pitch from the harpsichord or organ, but the difference in temperaments: strings tuning in pure fifths, and keyboards tuning in equal temperaments, proved to be problematic or from one of the winds, as the variance in temperature and humidity impacted wind pitches wildly: but which one?

Many instruments were considered for this role, including oboe, flute, horn, and trumpet. The narrow wiggle room for woodwind tuning led orchestras to buy all their wind instruments from a single maker as they would be consistent and be in tune within the set , and often, travelling players had to result in transposition. For a brief reference: the present scholastic research postulates that woodwinds in 18 th th century surrounded the A as we know it:.

But looking at the wild range for the tuning A, even from the narrow range of , the A still is on the move:. The oboe is particularly limited in its means of adjustment- the only pitch adjustment comes from moving the reed slightly in or out. String instruments have pegs to adjust tensions on strings, and the Brass has movable valves.

Clarinets can often adjust the length of their barrel; so, the orchestra adjusts to the oboe the bassoon is also a double-reed instrument, but as it sits lower, and harder to tune to it.

However, different reeds can shift the centre pitch, so the oboe is actually quite versatile, should the player have other reeds available. In addition, the players themselves can physically adjust, and they do have alternative fingerings available for intonation. The oboe, with its rich harmonics in the upper range, has a timbre than can project above the orchestra: so why not tune to the harp or even glockenspiel?

The glockenspiel, being made of metal, is one of the most constant and audible of instruments like the older tuning fork. Tradition: the oboe was incorporated to the orchestra quite early. Most symphonic pieces include an oboe or two. And their seating location right in the middle , makes them easy to hear for the whole orchestra. In fact, as many musicians tune with portable electronic tuners well before the oboe note, it is debatable whether such a ritual holds any practical value.

In the 19th century, a commission established by the French government tried to analyze pitch across Europe by looking at the frequencies of the tuning forks musicians used as their reference while tuning their instruments.

The commission gathered tuning forks from different cities, finding that most were pitched somewhere around hertz. Over the years, due to bigger concert halls and more advanced instruments, pitch was rising across most orchestras, and instruments and voices were being strained as a result. In , the French commission legally established diapason normal , the standard pitch for the A above middle C, at hertz.

The music world would still be debating whether or not pitch had risen too much more than a century later. Later, hertz became enshrined as a standard elsewhere, too. The agreement was eventually written into the Treaty of Versailles in
