No. That is used if there is a variable in the way of the problem within the parenthesis being able to solve itself. Since it can solve itself without the use of 'outside help', you would simply add 9 and 3 to get 12 etc. etc.

When a note in the bass hits (called the Attack), it doesn't sound very good. I don't know how really describe it other than it feels 'muddy'. Cleaning it up, or making it sound better, would be maybe lowering the level of the attack or putting an EQ on it and simply cutting them out all together.
I don't know if I can get any more simpler than that. The Music business is pretty specific when it comes to terminology.
Making the initial hit of the sound clearer. It just sounds like it was sampled too many times or something. Cleaning it up would cut out all those weird frequencies that make it seem like that.
Welp, Kim Dotcom just came out with a patent to the two-step authentication system, and is ready to sue a whole fuckload of companies if he doesn't get what he wants.
Great.
