Unfortunately, this range shrinks significantly as one gets older, and its upper limit usually drops below 10,000 Hz after the age of 55.For comparison, the audible range of mice is 1,000–91,000 Hz, and that of elephants is 16–12,000 Hz.Indeed, listeners reported that the writer, known for his incisive and sometimes stinging comments, seemed to have taken less than his usual part in the broadcast.He died only minutes after being loaded into an ambulance.The trumpet is one of the oldest known instruments, dating back to the day people first figured certain seashells and animal horns (adapted into instruments called “shofars”) made a great sound when one blew into them.Metal trumpets were made as early as 1500 BC, as both bronze and silver trumpets were unearthed in King Tut’s tomb.All three waveforms are periodic – they are made of a certain “basic unit” that repeats itself again and again; they differ only in the shape of this basic unit.These shape differences are the main (though not the only) factor that determines the timbre (“sound color”) of the note – through them we can tell the difference between the sound of a violin and that of a trumpet, for example.

Large parts of this theory are dismissed today as an esoteric mysticism, but those that deal with the mathematical regularity behind musical notes constitute to this day, about 2,500 years after they were formulated, the basis behind the theory of music.

Hexum was replaced in the series by Antony Hamilton, but the show didn’t last all that long, running only from 22 September 1984 to 6 July 1985 before being canceled.

Rhythm and blues recording star Johnny Ace died during a show he was giving in Houston, but did so offstage.

The number of cycles a wave completes in a second is called its frequency, and the unit used to measure frequencies is called Hertz (abbreviated to Hz).

The higher the frequency is, the shorter is the basic unit, and the corresponding note has what we call a higher pitch.

As the title of The Well-Tempered Clavier hints, Bach composed it for keyboard instruments that were tuned (or tempered – I shall use the two terms interchangeably below, even though they are not exactly the same) in a certain way – a way that was considered revolutionary at the time.
