Spontaneous music-making = spontaneous movement

[nodb]

Spontaneous music-making = spontaneous movement
Does we have to study "musically" in a slow practice-tempo?
Slower tempo = different musicality = different motions

What about spontaneous improvisations and their not rehearsed movements?

What are you asking?

Spontaneous music-making = spontaneous movement

Define spontaneous music making, are you talking about improvising? What is movement, you mean technique?

Does we have to study "musically" in a slow practice-tempo?
Slower tempo = different musicality = different motions

Usually we learn to memorize the notes, fingering and thus muscular memory associated with a phrase via a slower tempo. If you constantly play normal tempo you will generally hit more points of hesitation and inaccuracies which hinder our ability to memorize. Once the notes are learnt we can then apply the rest of the expression of the piece, however most of the expression is learnt straight away and no matter which slow tempo you play at. When you play slow tempo you can sometimes lose the understanding of the musical context of the notes you play but it is not something difficult to adjust yourself to, much easier than trying to learn every single new passage at normal tempo without hesitations/errors.

What about spontaneous improvisations and their not rehearsed movements?

Your hand movements while improvising have actually been rehearsed in pieces you have played before. Of course someone who has never played the piano who just randomly wiggles their fingers at the piano will have not any rehearsed movements, but it will sound like that too.

Thank you!

With spontaneous music-making, I mean the "spontaneous interpretation" of a piece.
With spontaneous movements, I mean not rehearsed motions or technique.

When we play a piece with a different interpretation each time, we use each time different motions.
Is it so important to study certain motions?
What about some technique books such as Breithaupt, Deppe,..., who said to use certain movements for certain passages in a piece? Certain movements of the arm, wrist, fingers,.. are (for me) ONLY for a certain interpretation.
