well this is my first time really attempting to play for a minute...(well that was prolly my 6 or 7th lol) its not hard on my muscles, its just like... playing straight double bass for that long you start to "zone out"...
i can play much faster... but not for a minute... however, id say that regardless of ancient wisdom - there is no real application for it... if there is a song that double basses for a minute straight it cant be a good one...
now if i were allowed fills every once and a while it would be alot easier... but still - i should NEVER have to keep it going that long... id say like... 32 measures max?(assuming im in 4/4)
maybe if i had a song to play to or something it would be easier to keep... but without that i just zone out...(thats why i switched up the beats a little, to keep me on my toes) and granted changing the beat around messed me up a bit, i couldnt play the same beat for a minute, let alone not mess up my double bass in that time
this was mainly for the people who thought i couldnt do cleaner doubles...
