I like
@Steve Freides ’ ideas of focus as it relates in a musical context, as I’ve just taken a break from practicing.
Purposeful practice is practicing with an understanding of what you’re trying to achieve through your practice and focusing on that aspect.
On the other hand, there is the interest in understanding the processes involved in making this possible ie the science behind the art.
Relevant to this topic, I think bodybuilders, with a natural instinct to growing a muscle, understood this intuitively with the “mind muscle connection”, a concentrated effort to specifically induce fatigue in the desires muscle group. I believe science has backed it up, as well, yet these bodybuilders didn’t really need it to succeed. These days, there is a greater understanding of this elsewhere, beyond my desire to comprehend or investigate.
However, I don’t see a problem I either understanding this, or just trusting that if something’s working, why tamper?
Proof in the pudding and different yolks for different eggs.
Science is constantly in flux as it’s subject, we, the earth, the environment, are. New data disproves data from a month ago and so on and so forth. Somethings, however, never change.
