Tuning fork is a tool used to pitch musical instruments.

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

Three crossed turning forks are in Yamaha brand logo.

Chords contain tierces (thirds).

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....

Tuning fork was invented by lute musician.

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

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

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

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

Chord consists of minimum three diffrent notes.

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.

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

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