I am raising this issue, which is a classic for everyone who plays an instrument. As is often the case, while playing a piece, a spring almost automatically triggers that makes us sing, grunt, or otherwise emit sounds that turn out to be annoying for the listener and castrating for expressiveness when we try to eliminate them out of shame. My teacher used to say that it is wrong to repress certain expressions that are so natural and somehow follow the music and manifest our way of understanding it, further stating that those who had repressed them in their youth would regret it in old age. What do you think? I manage to repress my incessant grunting with great difficulty, and it has also caused me several throat problems... pains, etc. What should be done? It wouldn't be bad to talk about it. Thanks to everyone.
Breathing is important for the pianist. Sometimes the accentuation of rhythm, the intensity of expression, etc., cause in us contractions of "participation" in the musical "tension," and it is right not to suppress them. The important thing is that they do not stem from worries about difficulties. That is, they should not translate into efforts, contractions, or stiffness of muscles or internal organs.
Many Greats have also had and have had this behavior of "participation." I remember Rubinstein breathing heavily, but, up close, his "breath" seemed to be part of the music. Brendel sometimes grunted. Gould actually sang (we can hear it on the recordings). I believe it is inevitable and not "suppressible."
In reality, this can be heard up close......But if our sound becomes truly "public" (sometimes even the "piano"... is not piano...), then the "grunting" remains confined to a short distance and moves away from the sound, which expands far out.
