Oscilloscope

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

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

Highest note define the position of chord.

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

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

Chords contain tierces (thirds).

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

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.

Tuning fork was invented by lute musician.

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

Three crossed turning forks are in Yamaha brand logo.

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.

Tuning fork is a tool used to pitch musical instruments.
