Laryngologists use tuning forks in 432Hz becouse that's the frequency human body transcribes the best.

The first of real time computer games was made for oscilloscope. "Tennis for two" was programmed by William Higinbotham in 1958....

Nowadays there are many kinds of spectrum analyzers: stationary, portable, handhled and networked.

Tuning fork was invented by lute musician.

There are two types of spectrum analyzers: swept-tuned and time-sequence.

Three crossed turning forks are in Yamaha brand logo.

Osciloscopes are used not only in the audio (music) industry, but also science laboratories, hospitals and clinics.

Highest note define the position of chord.

Following the discovery of fast Fourier transform, in 1962 the first spectrum analyzer was engineered.

Chords contain tierces (thirds).

Key attributes of networked spectrum analyzers include the ability of synchronize data captures and effortless free acces.

Chord consists of minimum three diffrent notes.

In 1897 german physicist K.F.Braun engineered the first oscilloscope.

There are two type of chords- consonant chords and disonant chords.

Drum sounds can't be compononents of a chord. Chords can only consist of certain notes.

Oscilloscopes are used to observe the change of electrical signal over time.
