I disagree, it's like comparing traditional grip vs matched grip vs french grip and saying "use only traditional grip", both heel-down, heel-up and toe-heel are "legitimate" techniques, it's a personal choice.
No, it's like comparing push-pull to bouncing to Moeller to Gladstone. You can use whichever you like to play doubles and triples, but they shouldn't be a crutch you depend on to play, and you should always be working on your "regular" strokes.
I disagree again, within my 30 years + at the kit, I have really studied the different bass drum techniques, as the kick drum is my favourite drums, and I opted for the heel-up technique which I use all the time and I have no problem whatsoever with consistency, dynamics and speeds. It's what the drummer will find more suitable and/or confortable that the deciding factor
That's great for you. Everybody should spend their time investigating all of the various methods for playing the drums and figure out what works for them. You can glean different perspectives from studying various methods, and it will make you a more well-rounded, understanding, and complete drummer. If you only pursue one method and put all of your chips in that one hat, you don't have the advantage of a bigger perspective. The original poster was asking which specific technique he should use, and I was telling him to work on his basic strokes. There should be no issue with that--that's basics. The pedagogical reason I was telling him to practice heel down was so that:
1. He produces strokes from a neutral, relaxed initial position.
2. He has less chance of "sneaking in" his previously-mentioned tricks while working on the basic strokes, which all start from a heel-up position.
If you switch techniques, Michael Packer (
http://www.youtube.com/user/mpacker49?feature=mhum#p/u/2/dPQqqf_-BSg) explained the importance of the pre-position of the foot
before any stroke with any technique. it allow the foot to be ready for the upcoming stroke, without the pre-position of the foot, consistency and accuray are at risk.
...hence the heel-down suggestion for practicing. Sure, you can have a pre-position while playing heel-up, but most people I know who play heel up rest their foot/leg between long pauses between notes, and do the foot equivalent of a "prep stroke" before playing the first note after that long pause. It's not as consistent as heel-down, where your heel is planted on the plate.
Therefore, you can switch techniques, providing you use the pre positioning concept and that you're aware of what you want to play at ALL times.
This is why I would suggest concentrating on the music rather than which pre-position you want to use for which technique you want to use. Have a foundational grounding in the basic strokes, and you won't have to worry about technique, just playing music.
Ultimately, the truth is, every technique you study, every style you play, every drummer you emulate, every lesson you're taught, etc., all have something to offer. Take from it what you can and incorporate what makes sense to you as a player. Heel-up players have a LOT to learn from playing heel-down, just like heel-down players have a LOT to learn from playing heel-up. I play both, and have studied all of the "tricks" we've been talking about extensively. I'm a better player because of all of the practicing, and I've learned from each new perspective. I'd recommend that the original poster do the same--study and practice as much as you can! Don't stagnate or get stuck in your ways...there's always something new out there to learn that will help your playing and keep you growing as a drummer...
...but that's just my opinion. Good luck!
