Tuning fork was invented by lute musician.

Use of spectrum analyzer provides a plot and trace of signal amplitude in the frequency domain.

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.

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

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.

Chords contain tierces (thirds).

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

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

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

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

Tuning fork is a tool used to pitch musical instruments.

Chord consists of minimum three diffrent notes.

Highest note define the position of chord.

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