Example of the hit song ingredient Key

Different scales produce different feel.


For example a piece of music written in a scale that has all the white notes and therefore chords with white notes feels very different to one written mainly on black keyboard notes.


An example is the beautiful Chariots of Fire - Vangelis. It is written on the C sharp major scale. Most notes of this scale are black.

Playing this piece on the piano to a 4 year old kid at the original key and then to the nearest one ie the C major key which has all the white notes makes a tremendous difference. It is almost impossible to listen to this piece of music on C major. When the piece was replayed at the original C sharp major everyone including the kid who possibly had just heard the piece for the first time in its life was relieved with joy.


Why such a difference?


Does the piano sound better on black keys? (The piano used must have been tuned to roughly A4
447Hz).


Is the inner ear basilar membrane a body in itself?


Transposing a piece of music means change in the frequency domain and so different adjacent parts of the basilar membrane are caressed by the hair cells.


Who caresses who? The basilar membrane caresses or is it being caressed?


Is it like a cat rubbing itself around our leg? Is the leg caressing the cat or the cat caressing the leg? Or does the cat want to get rid of some hair because it is summertime?


Another example of a beautiful scale is B minor. It feels in a certain way. An example is The Great Gig in the Sky - Pink Floyd.

In fact B minor does not stay for long as the piece is modulating to G Dorian, which has only the black note of B flat.
It seems impossible to listen to this piece at a different scale or Key. Why? Perhaps it is because the composer Rick Wright made this piece by improvisation, he was guided by what he heard. It is the music that drive us, not we driving the music.

Is there a theory that explains why different scales produce different sensations to our soul?
