The principle of least change in music (laziness) part 2

The least the change of notes form one chord to the next the better and more sophisticated it sounds.


An obvious example is:


Vocalise - Rachmaninov
When playing it on the piano using the piano vocal score, most of the fingers stay in the same position playing the same notes while one of the fingers is changing to a different note.

In pop music too.


For example:


Tonight - Reamonn


Also written in the E minor key. (All notes are white except F which is F sharp).


At the chorus the harmony code using Bach's notation or figured bass is:


A9    Oh Ton
D     ight You ki
B7   illed me with your
C7   Smile so
A7   beautiful and
D     Wild so
B     Beautiful and
E     Wild


If one tries to play (on a keyboard instrument for example) those chords it can be clearly heard that the implementation with the least change in nearby notes sounds the best. Sevenths and ninths are prepared for our brain as Bach and Niedt explain.
