It's interesting on how Steven White says to work on the second note of the double because Tommy Igoe ( great teacher drummer) says work on the FIRST note of the double- not the second note which is the opposite of what we've been taught. Reason? The big brother first note is a bully to the little brother second note in which the second note will NEVER be equal to the first note and it's just a matter of lessening the bulliness of the first note to EQUAL the second note😊👍🏻 @robknopperstudio
