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

Highest note define the position of chord.

Chord consists of minimum three diffrent notes.

Chords contain tierces (thirds).

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

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

Three crossed turning forks are in Yamaha brand logo.

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

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

Tuning fork was invented by lute musician.

Since 1939 binding sound for pitching musical instruments is in 440Hz frequency. Formerly it was 432Hz.

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

Tuning fork is a tool used to pitch musical instruments.

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

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

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