I had to do a separate post about this as I think that last week's "Mad World" was the most fabulous performance Adam has done on Idol to date. His tone was so pure and clear - he faltered a few times but the whole song was haunting. The blue lighting made him look other-worldly - almost ethereal.
Many reviewers picked on him because of his last note. Quite a few musical morons said he was sharp. DUH - newsflash everyone, he was NOT sharp. In fact, that note was so far at the top of his range I still can't believe he hit it. It sounded almost if he scooped the note, but I believe he really wanted to hit it square on. If you look at the video you can see how wide his mouth was and how he was supporting the note with his whole body. Problem was for him is that he didn't quite hit it straight on, so he FIXED IT by forcing his palate up just a bit higher...and the note became in tune.
Here's a link to it: it's been pulled from Youtube...but a fan club site has it.
Now, if you're not a singer you haven't a clue as to what I'm saying - but that's ok. Even if you know what the palate is (I'd bet most people don't - if you did a "Jay walking" episode on it!) you probably don't realize what part it plays in singing. Normally, if you're already tense, and you know you blew the note, the LAST thing you'll be able to do is correct it by posture and palate - in fact, you'll probably be so tense it will get WORSE. That made me even more impressed with him - that he could correct the flaw effortlessly.
