Thank you for your answer.
In fact, I have no audience to conquer, I play for my own pleasure.
I have taken a very bad habit from working with teachers that made me play great pieces without establishing the fundamentals of music : rhythm, harmony, melody and piano : sight reading, control of separate voices and/or hands.
The result is that I cannot play without saying the name of the key. To get rid of it, I would like to say (in my head) either the beats or a onomatopea (don't know if there is such a word in English) like oum pah oum pah or ta ke ti mi ,ta ke ti mi (like the Indians do) or anything else if it gets me rid of the name of the keys.
I study with a method of improvisation by French jazz pianist Martial Solal.
It starts with four beats with the left hand.
I have spent three hours last night (!) trying to create a real rhythmic section. I am absolutely sure by now that rythm is the bases of it all.
Unfortunately, in France, the way rythm is taught is very intellectual, more mathematics than music.
So instead of developing a natural sense of rythm like africans, gypsies..., it sterilized my natural sense of rythm. After all, my heart is very rythmical, so I have it in me.
I like it when I can really exchange with a skilled musician.
In fact, I am learning the first fugue of the Well Tempered Clavier (C major) and I would very much like to have a stable rythmic basis to give unity to this complex counterpoint.
So, the oum pah question is not completely irrelevant.
I am really trying to find a way that makes music available to people who were not lucky enough to benefit from the traditional teaching methods and therefore are like poor souls in the Purgatory, wandering forever in search of music.
Have a nice day.
