yea just back on friday, my band jammed and i kept making mistakes. kept screwing up and sweating and using excessive strength. WHY?
The drum throne screwed up, kept going lower and lower as i played.
I need more strength than usual on the pedals, couldn't reach the cymbals with ease, couldn't do good tom rolls, and sticks kept hitting the rims hence giving off unnecessary rimshots, till the extent my sticks fell out of my hands. I really sucked on friday. Oh ya, not to mention, for me, the lower the throne, the lower my confidence.
So when the studio ppl changed my chair shortly after i cursed and swore at an inanimate object, (the throne), my confidence was back to at least 90% and i was so comfortable.
So, keep your thrones high and comfortable to your level. Good posture= good playing.
cheers.
