pit's change is a real a serious issue
that threatens for our musicians but
isn't the pitch boys changing what
exactly is pitch change anyway and why
should we care when we talk about pitch
change you might think of altitude
playing vibrato
a piano that really needs to be tuned or
even just lack of practice but the pitch
change I'm talking about today refers to
the drastic rise in a levels of the last
400 years scientific research has shown
that the average levels of a are in the
1600s was around 415 Hertz now by the
late 1700s and early 1800s this level
has raised to 432 432 Hertz and now
today a levels rest well over 440 Hertz
in the last decade alone in Australia
orchestras have risen from 440 to 442
Hertz Europe is suffering much more with
orchestras and pianos these days being
sued to 443 444 hurts sometimes even 440
a equals 448 Hertz
this is record breaking high levels of a
ninety seven of pitch change scientists
agree that this phenomenon is caused by
human activity more specifically from
harmony the human desire to be heard
because by playing a little bit sharp
the bright Tambor and the tension allows
you to cut over your stand partner thus
allowing you to stand out from the rest
this tendency to want to be heard above
others and project has caused a levels
to steadily rise over time one of pitch
changes biggest victims is the
instruments for singers who use their
bodies as an issue
they risk a shorter and shorter
performing career as the forces of
higher and higher the restraining device
as pitch increases the damage done to
our ears by high treble instruments also
increased the piccolo is already too
damn high
does not need to go higher the e string
on the violin will also begin to sound
increasingly shrill causing more
violinist to opt for the viola instead a
very tragic compromise so as a levels
continue to rise treble instruments risk
becoming endangered even extinct pitch
changes we know today has massive and
permanent ramifications although it is
here threatening there are things that
all of us can do individually to prevent
it from getting worse
first of all use it sooner and refuse to
tune above 442 Hertz for a now if you
want to go the further mile you could
even decide to start your own
historically informed barak performance
ensemble and tune a course for
everything the main takeaway is that
pitch change is a real a serious issue
but although we are all part of the
problem we can all be part of the
solution as well
