Well pitch can be explained in two ways

• Technical way
• Practical way

Technical Way

Pitch is nothing but, it is the value or frequency of sound of a particular key. The key A (A4) will be right in middle of the piano, has value of 440 hertz.

440 hertz means 440 cycles or vibrations per second.

For example let us think that if the frequency of key ‘C’ is ‘x’ then the frequency of next ‘C’ key will be ‘2x’, similarly if the frequency of key ‘C#’ is ‘y’ then the value of next ‘C#’ will be ‘2y’, similarly apply to other keys also.

Therefore if the frequency of key ‘A4’ is 440 hertz then the frequency of next key ‘A5’ will be 880 hertz.

This is how the frequency changes from one octave to other. Do remember that no two keys or no keys will have same values. Every key will have its own frequency.

Practical way

Let us play the two lines of ‘Vandemataram Song’ in different types

Type – 1

Vande Mataram – C4D4  F4G4F4G4

Vande Mataram – F4G4  B4C5B4C5

Type – 2

Vande Mataram – C5D5  F5G5F5G5

Vande Mataram – F5G5  B5C6B5C6

The difference between these two types is first type is played in lower pitch, where as second one is played in higher pitch. The pitch has been raised in type 2 context.

But do remember that both are played in same scales since same keys are used. The only difference is pitch.

This is how you need to understand the pitch in the context of ‘technicality and practicality’

What is Pitch in ‘Piano’ ? – Video Tutorials

If you know a song from one minor scale and want to shift that song to other minor scale, then what is the process ?

Initially let us select any two minor scales and a song.

For example here we have selected a song (Kyunki Tum Hi Ho…….), which will be played in  ‘F’ minor scale and will be shifted to ‘A’ minor scale

(How ever you can select your own song and scales of your choice)

Let us understand ‘F’ minor scale

• Any major or minor scale will have basic 8 notes. In ‘F’ minor scale the key ‘F’ is known as root key or 1st note or 8th note.
• The notes which are on right side of ‘F’ are known as high notes and which are left to ‘F’ are known as low notes.
• The order of notes will be in this way, High notes – F-1, G-2, G#-3, A#-4, C-5, C#-6, D#-7, F-8. Low notes – F-8, D#-7, C#-6, C-5, A#-4, G#-3, G-2, F-1
• The numbering system is same for both low and high notes, the only difference is the right side notes are high notes and left side notes are low notes with respect to basic key ‘F’

Similary ‘ Let us understand ‘A’ minor scale

• Similary in ‘A’ minor scale the key ‘A’ is known as root key or 1st note or 8th note.
• The notes which are on right side of ‘A’ are known as high notes and which are left to ‘A’ are known as low notes.
• The order of notes will be in this way, High notes – A-1, B-2, C-3, D-4, E-5, F-6, G-7, A-8. Low notes – A-8, G-7, F-6, E-5, D-4, C-3, B-2, A-1
• The numbering system is same for both low and high notes, the only difference is the right side notes are high notes and left side notes are low notes with respect to basic key ‘A’

Now the number pattern for these below four lines in ‘F’ minor scale will be in this way (watch below video)

Kyuki Tum Hi – 3 4 5, 3 4
Ab Tumhi Ho – 3 4 5, 3 4
Zindagi – 2, 4 3
Ab Tum hi Ho – 2 1 2, 7 1

(* 7th note is low note)

Now apply these numbers in ‘A’ minor scale or any minor scale, you will get the same tune and same song.

So, just try to note down the numbers of one minor scale and apply it to other minor scale as simple as that.

At the end of the day you need to understand that this number pattern formula works only for the scales which are similar in nature, like both have to be major scales or minor scales. This pattern will not work for major to minor or minor to major.
