# Common Musical Geometrical Ratios

Common Musical Geometrical Ratios. First, what is a ratio?

Musically, in the diagram above: Every time a higher tone vibrates four times, the lower vibrates three. This creates the sound of a perfect fourth. All the perfect intervals and most harmonious tones of nature can be found at a bowling alley. Also, in the link below I explore the ratios of 6 to 5 found at Atlantis.  The size of an interval between two notes may be measured by the ratio of their frequencies. When a musical instrument is tuned using a just intonation tuning system, the size of the main intervals can be expressed by small-integer ratios, such as:

1:1 (unison),

2:1 (octave),

3:2 (perfect fifth),

4:3 (perfect fourth),

5:4 (major third),

6:5 (minor third).

### Below are the only the Perfect Intervals found by bowling pins in an alley

• The unison becomes the single, front standing pin.
• The perfect octave is the 1st pin divided by the 2 pins in the 2nd row: 2:1 is the higher octave.
• A perfect fifth is the ratio of the 3 pins in the third row divided by the two in the second: 3/2.
• As mentioned, the 4 divided by the 3 makes the ratio of the perfect fourth.
Ratios are often used to describe other items as: The ratio of width to height of standard-definition television.

In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second.[1]

## Clues in the Search for Atlantis Come With # 5 and #6.

When it comes to music, Atlantis lives!

Plato wrote of Atlantis in Timaeus that numbers 5 and 6  were prominently featured: People were gathered every 5th and 6th years alternately: Thus giving equal honor to odd and even numbers. The gathering of the population was for judgement and atonement.
