Octaves

As we know, a set of 12 keys (7W + 5B) repeats on an instrument.

This repeating set is called an Octave.

Considering a standard 5-octave keyboard,
every note appears 5 times on the keyboard.

To uniquely identify and write each note, let us first give unique names to the octaves as seen from the below diagram.  

A standard 5-octave keyboard

So from the above diagram, we see that the different octaves are represented with the help of dots above or below the reference note.

But can we simply number the octaves? 

Can we name the notes as C1, C2, C3, C4 and C5?

Note that many instruments having different number of octaves. Few Examples:

  • Harmonium – 3.5 octaves
  • Guitar – 4 octaves
  • Standard Keyboard – 5 octaves
  • Piano – 7.5 octaves (highest among all) !!!

Hence, considering piano as the reference, the notes are numbered according to the octaves.

So, the answer is YES.

And C4 is considered as the middle octave across all instruments.

Music Wheel

The music wheel consists of 7 musical notes i.e C, D, E, F, G, A, B. This music wheel is the base foundation for naming of musical notes.

We have only first 7 alphabets (7 shuddh swar) in music which forms the music wheel. 

For instance – A, B, C, D, E, F and G.

The musical alphabets start with C

For instance – C, D, E, F, G, A, B and C.

Memorize this diagram in both clockwise and anti-clockwise directions.

Let's take an example of a standard size keyboard

We can observe that –

The music wheel (7 white keys) repeats in clockwise direction from left to right.

Broadly, a set of 12 keys (7 white + 5 black) repeats at regular intervals on the keyboard.

Remember that the C note appears immediately on the left hand side of the 1st black key of the repeating set.
