She critiques all of them --here's what she said about Kris this week:

KRIS ALLEN 23- years old: “How Sweet it Is” by - Marvin Gaye

Strengths: Kris - you decided to “change it up” this week and choose an up-tempo song. This was a great song choice. I loved the slow, sexy start to this song - it was a teaser to the clever movement into the gritty uptempo portion of the song. Through your playful facial expression, you visually mirrored the tempo change to perfection. I love watching you - your natural expressiveness establishes such a bond with the audience. You bring all of us along for a whimsical musical ride.

You are also so very musical, as evidenced by the manner in which you punctuated the rhythmn through the strumming technique on the guitar. There is always a forward momentum in your musical line and, yet, it always looks and sounds perfectly controlled. You are extremely masterful in setting just the perfect pace for your songs.

Your voice sounded beautifully resonant and clear. It is such a gorgeous instrument and you moved seamlessly throughout your range. Do you have perfect pitch? You really have a way of centering your pitch, even if the technique is not where it should be at this moment in time. The lightness of your voice - resplendent with head resonance - is probably the reason for this. Your voice has clarity and transparency that is ubiquitous throughout your range.

I also appreciated your attempt to maintain a circular mouth formation and relaxed jaw. You were really trying to apply a cohesive approach to myour vowels and, as a result, your voice sounded wonderfully resonant

Also, the performance structure appeared effortless and, more important accented your genuine distinctive style. Although this was a well-rehearsed song selection, it appeared and sounded spontaneous and because of this, it felt and looked authentic. This is a signature Marvin Gaye song, but, in your aw-shucks way of performing, turned it into a Kris Allen signature song. And that is what this competition is really about - re-arranging and modernizing music from the past!

I absolutely loved this performance Kris! Bravo!

Critique: Kris -careful that the tension in the neck and jaw doesn’t get out of control No head-raising on the final note - that’s not a good thing! Always think down when moving up - think over the note, never reach for your upper note. This approach will only cause needless tension. And bend you knees and squeeze that butt, breathe, drop your jaw and - presto -watch the magic happen.

Over time, I know all of this will improve and you will feel a more profound resonation process. However, your performance this week was a spectacular one and I. Loved. It!
