Hi! I am Roman Senyk from

Ivano-Frankivsk in Ukraine.

This lesson is for week 1 of

Introduction To Music

Production at Coursera.org.

Here I will be presenting the

topic F y .

So what it is?

Frequency

Frequency –

physical quantity equal to

the number of repetitions or

the occurrence of events

(processes) per unit time.

Frequency is measured in

Herz (Hz)

A human ear can hear

the waves with a

frequency of

20 Hz to 20 kHz

Sound with a frequency lower than 20 Hz is called infrasound

Sound with a frequency above 20 kHz is called ultrasound.

In music we

commonly use sounds

with fundamental

frequency of

sub-contra octave to

5th octave

Harmonics

However, musical sound usually

does not consist of pure sound of

the fundamental frequency, but

also from harmonics added to it.

A harmonic of a wave is the part

of a signal's frequency that is a

whole multiple of the fundamental

frequency.

Overtones

An overtone is any frequency

higher than the fundamental

frequency of a sound.

Overtones of musical sounds are

accessible throughout the hearing

frequency range.

World Standard

Pitch A440, which has a

frequency of 440 Hz, is the musical

note A above middle C and serves as a

general tuning standard for

musical pitch. Prior to the standardization on 440 Hz,

many countries and organizations followed

the Austrian government's 1885 recommendation of

435 Hz. The American music industry reached an informal standard of 440

Hz in 1926, and some began using it in instrument

manufacturing. In 1936 the American Standards

Association recommended that the A above middle C

be tuned to 440 Hz.

Well,

’ a a y about

Frequency spectrum

Bass range

of

frequency spectrum

These are the lowest notes which make the room resonate. These frequencies are responsible for

the fullness, depth and energy of sound.

In this range we can hear kick drum, bass guitar, double bass, tuba, distortion guitar chords

etc.

When recording, you should be careful not to lose these

frequencies. It is always better to cut them at the mixing phase.

Middle range

of

frequency spectrum

Located here frequencies always are

responsible for rhythm and

accompaniment, also this is guitar

register.

Boosting higher spectrum of this

range allows us to achieve bright,

sparkling sound, creating an effect

of the presence because there are many harmonics and overtones.

High range

of

frequency spectrum

This is the extreme hearing range, however the

frequencies go even higher, up to 300 kHz.

Here we can find the most subtle and delicate

frequencies, sibilance, noise of tape etc.

I y ’ ay attention to this range you can feel some discomfort

while listening.

Equalizer or EQ This is an audio processor which uses a combination of different filters to alter

the balance of frequencies in an audio signal.

This instrument allows us to work with certain frequencies, boost or attenuate

them.

There are two types of EQ: Parametric and Graphic.

With EQ we can manipulate the timbre.

Timbre

Also known as tone color or tone quality.

In simple terms, timbre is what makes a

particular musical sound different from

another, even when they have the same pitch

and loudness. For instance, it is the

difference between a guitar and a piano

playing the same note at the same loudness.

Thank you!

Thanks for reading, guys.

I hope you enjoyed it as much as I did while working on it.

I would like to read your comments, suggestions, and

criticism.

If I left out some important information just let me know.

Bye!
