Adele blames 'piano mics' for Grammys audio issues

Singer Adele has blamed the falling down of piano mics for strange guitar tuning sounds during her performance that was marred by technical issues at the 58th annual Grammy Awards here on Monday.

"The piano mics fell on to the piano strings, that's what the guitar sound was," the British star, who performed "All I ask" at the music ceremony, wrote on Twitter, reports people.com.

"It made it sound out of tune. S--- happens. X."

The star kept a positive attitude, despite appearing visibly upset during the broadcast. In fact, Adele decided to wash away her musical sorrows with a treat at popular fast food joint In-N-Out.

"Because of it though... I'm treating myself to an in n out... So maybe it was worth it."

Neil Portnow, the president of the National Academy of Recording Arts and Sciences, told reporters that it was an issue of too many complicated performances.

"We had the most complicated show on television. Period. End of story," he said.

"With each musical performance, we change over the microphones, the wires. I mean, if you've been backstage - I can't understand how they get it done, but they do.

"So, from my understanding, the microphone in the piano was knocked into the strings inside of the piano, so what was done there - and these things happen - the engineer people had to switch over on their backup system, so to switch over on the backup system, they had to back out for a couple seconds in the house here, and that's what happened."

"All credit to her for how professional she is," he added. "She did a great job and we certainly don't like when those things happen, but those things happen sometimes."

Some fans on Twitter speculated that the twangs heard during the performance were caused by Justin Bieber, who performed with an acoustic guitar after the British singer.
