Should i learn all intervals in every key? or sohuld I just be able to do that? I am able to do this but I don't know.... maybe I should know them by heart...
i didnt learn all intervals but i learned intervals like 1/8, 3rds, 5ths, 7ths. From these knowing my formulas i can find all the intervals easily
yeah just learn the formula's and names, like learning the key signatures, learn the formula then learn to not use ya fingers and after time it will come naturally like times tables.
the intervals are the same in every key, do you mean the intervals of each scale? you just have to play the scales and see how they work...learn interval shapes on the guitar and familiarize yourself with each interval's particular sound and feel; training your ear is great practice and is endlessly helpful
