The human
ear, under optimum conditions and depending on age, can hear between 20Hz and
18kHz. That’s pretty rumbly, low frequency sounds and pretty high ones too. But
not as high as a dog-whistle, which we can’t hear; although the Beatles still enjoyed asking their engineers to cut one in to a song on one of their albums, to the consternation
of puzzled dogs and dog-owners all over the world.
It’s a
remarkable thing, our ability to hear. It’s our oldest sense – the first
sound we ever hear is at 18 weeks and it's our mother’s heartbeat in the womb. Which is why music
centres on tempos akin to our various heart beats, and breathing.
Normal
breathing is around 12 to 20 cycles per minute, so 3 to 5 seconds per in-and-out cycle. But
during sleep or meditation, this can relax down to between 6 to 8 seconds per cycle.
And you know that feeling of well-being we get from being at the sea shore? That stems from
the fact that our breathing has a tendency to synchronise to the rhythm of the
waves, which happen to be 8 seconds apart.

Before each
performance all the players sound the note of Concert A, at 440Hz – you’ll have
heard that sustained note sounding across the platform before a concert starts –
but that note actually moves in absolute pitch depending on who is tuning the oboe, or who has
tuned the piano, if a piano is part of the performance.
Because a
piano may need to be tuned ever so slightly sharp, so that it sounds crisper in
the top register than it might with a straight 440Hz Concert A. So everyone else
has to adjust slightly. Not much, but enough to stay in tune. This will affect
every instrument, as each player knows precisely where their perfect A is, and
it will particularly infuriate the violinists as it shifts their beautiful
overtones; but for a melodic and tuneful end-result, they all have to adapt to
fit around the requirements of the pianist, or the oboist, or the harpist.
That’s how a 90 piece symphony orchestra achieves harmony, not just once, but for performance after performance after performance.
Maybe you could think of your company as being like an orchestra, with you as the Conductor. Listen carefully to your business as it rehearses and tunes, and start to hear where the harp is, where the oboe is, where the piano is and
where all the violinists are; and then maybe you can use this analogy to understand
where you need to be applying some fine tuning to enable your own concert
orchestra to deliver a symphony in tune, on time and all together.
That
Beatles track? It’s the last one on the Sergeant Pepper album – 'A Day in the
Life'. Put it on at home and watch your dog tune in and turn on...
