Tuning fork is a tool used to pitch musical instruments.

Tuning fork was invented by lute musician.

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

Some artists use oscilloscope waveforms to make certain patterns. They are able to create eye-catching mandalas or floral shap...

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

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.

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

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

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

Chords contain tierces (thirds).

Chord consists of minimum three diffrent notes.

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

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

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