Watch: Jeniffer Hudson's Tribute To Whitney Houston At The 2012 Grammy Awards

With the loss of one of the music industry's brightest talents only two days before the 2012 Grammy Awards, it was obvious that Whitney Houston would be at the forefront of everyone's mind during the ceremony.

Adele has finally returned to the spotlight after months out of the public eye, healing from surgery on her vocal chords following a vocal hemorrhage last year. And what better time to make that return than at the biggest music award ceremony on the calender, the 2012 Grammys. Not only performing tonight, the singer is also nominated for six Grammy awards, including the coveted album of the year for 21.

Rihanna kept the energy levels up at the 2012 Grammy Awards Ceremony, delivering perhaps one of her most choreographed performances to date.

Her vocals during the piano led intro of We Found Love sounded good but became more pitchy as it progressed with her using some melisma to quickly get away from the missed note. However, once the substantial backing of the song started, she hit her stride, dancing and belting the notes, with a rasp at times, almost perfectly.

Adele's First Vocal Performance of 2012, After Surgery. But Has Her Voice Recovered? Listen and Judge For Yourself

Thank the heavens, Adele's voice is back! After the trauma it had been through last year [read more] and the vocal chord surgery, I was worried it would go the way of Julie Andrews', and come back a damaged instrument! Thankfully, this hasn't happened. Listen below!

Tarja Turunen- Vocal Range/ Profile [Lyric-Soprano: 3 Octaves]

Tarja Turunen

Vocal Type: Lyric Soprano
Vocal Range: 3 Octaves 1 note and a semitone (F3-Ab6)
Whistle Register: No
Vocal Pluses: Tarja Turnunen's voice has a duality to it that has been created by her classical training and her time in a rock band. Thus,she can create a sound that is operatic, but equally adapt to sing in a more contemporary tone.

The low note are achieved comfortably with great support, creating a controlled and measured tone that moves into its midrange with brilliant mirroring of timbre and tone. The head voice is the strongest part of Tarja Thunrunen's voice, thanks to its classical training. It's full, rounded and with a sweet timbre. It can create a resonant operatic tone, creating stunning crescendos, or utilise a softer timbre that contrasts texturally, but that's not so resonant. As the head voice climbs higher, towards the sixth octave, its colouring remains bright, polished and its tone stays clear and resonant, though less powerful than the lower half of the head voice- hear the introduction to Damned and Divine.

Tarja Turunen's brilliant technique allows for sweeping trills, resonant held notes and the implementation of a classical vibrato that is beautifully executed with even spacing.

Vocal Negatives:Over reliance on head notes, but that may be solely due to the type of music she sings. Still, it would be nice to hear how her belting range sounds in the fifth octave.

Christina Aguilera: "The Voice" Season 2, Prince Medley

Hit American talent show, The Voice, returned to spectacular ratings of 35 million plus viewers! It has to be said that this must have been helped, to a large degree, by it following the 2012 Super Bowl, because its first season was averaging 12 million. For reasons unbeknownst to me, the judges decided to sing a medley of Prince songs to open the second season with. NB:I don't watch the show so let me know if there was a reason.
