Curious, I checked out the website and found this: "Create and share songs with friends or sing with the Glee cast. Glee will correct your pitch and harmonize your voice while you sing." Wow, how very innovative!
I was impressed at the songs sung by various Glee fans (all over the world!) that I have listened to so far. Given a chance, I'd like to try that application out for my, and my family's, personal entertainment. I think my husband would enjoy exercising his lungs LOL. Unfortunately, I don't own an iPhone or iPad --- yet (wishful thinking!) So I guess I'd just continue singing "Defying Gravity" and my other favorite Glee songs in the shower :)
But, for those of you who do have the required gadgets, you might want to give it a try. And if you do, please post the link in the comment section of this post so I can hear you sing!
