The next pitch is called the octave because it’s the eighth note (just as an octopus has eight legs). More than a thousand years ago the letters of the Roman alphabet were adopted to refer to these, and since there were only seven the letters ran A, B, C, D, E, F, G.

How to Draw a Lewis Structure

1. Step 1: Find the Total Number of Valence Electrons.
2. Step 2: Find the Number of Electrons Needed to Make the Atoms “Happy”
3. Step 3: Determine the Number of Bonds in the Molecule.
4. Step 4: Choose a Central Atom.
5. Step 5: Draw a Skeletal Structure.
6. Step 6: Place Electrons Around Outside Atoms.

To say that a note is one octave higher means to say that the note is the same, but it is in a higher section of the instrument. Imagine a piano. On it, the keys on the left are lower than the keys on the right. As the notes get higher, it is easy to see that the next C will be higher than the previous one.

7/5 tritone 10/7 also called a tritone. The idea behind twelve is to build up a collection of notes using just one ratio. The advantage to doing so is that it allows a uniformity that makes modulating between keys possible.

In the western musical scale, there are 12 notes in every octave. These notes are evenly distributed (geometrically), so the next note above A, which is B flat, has frequency 440 × β where β is the twelfth root of two, or approximately 1.0595.

The twelve notes of the octave—all the black and white keys in one octave on the piano—form the chromatic scale. The tones of the chromatic scale (unlike those of the major or minor scale) are all the same distance apart, one half step.

Amid a list of powerhouse vocalists like Adele, Whitney Houston, Aretha Franklin, Alicia Keys, and more, one Axl Rose reigned supreme with a mighty range of five octaves.

The vocal range of Celine Don is Bb2 – C6 – E6 with the most extended note of 15 seconds duration. Her vocal type is Lyric Soprano with three octaves and three notes.

Some say that very soon,his range will move to 4 ocataves. Wait and see! This video is a compilation of “My world” albums,still young voice,many falsettos(specially on “Baby”),but I can´t agree about 8 octaves range,no one can do that,but you can clearly hear C#3-E5.
