« on: April 26, 2018, 06:30:16 PM »
This topic has an informative character and contains basic elements from Music Theory!

1. The Sound = vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.

- (musical sounds ) – pleasant sounds  (the sound of a musical instrument)
- (non musical sounds) – for exemple sounds produced by falling objects which disturbs the human ear.
- Humans can only hear sound waves as distinct pitches when the frequency lies between about 20 Hz and 20 kHz. (20Hz - 20.000Hz)

2. Musical Notes

Musical Notes have 7 names : C,   D,   E,    F,   G,      A,   B. (international notation)
                                              DO, RE, MI, FA, SOL, LA, SI.

Notes are grouped in octaves (eight notes, from C1 la C2 - C1 D1 E1 F1 G1 A1 B1 C2) every each musical note has a specific frequency (in the image the frequency is typed with red color):

3. Scales

Musical Scales are a series of musical notes selected in a specific mode from the notes of an octave.

Types of Scales:

Major Scale
Minor Scale
Harmonic Minor Scale
Melodic Minor Scale
Pentatonic Scales

The most used are the Major and Minor Scales (in the image the green dot represents the beginning of a scale followed up by the rest of the scale notes which are the orange dots):

3. Chords

Chords are a group of notes which can be played together and can function as melodic harmonies.

Chords build from 3 notes (triads):

Major Chords:

Minor Chords:
