(CNN) -- On the day of George Jones' death, several musicians were in mourning over losing not only a great talent, but a great friend.
"My heart is absolutely broken. George Jones was my all time favorite singer and one of my favorite people in the world," Dolly Parton tweeted Friday. "My heart goes out to Nancy and the rest of his family."
Country singer Brad Paisley, who recently kicked up some dust with his country/rap collaboration with LL Cool J, shared a lengthy reflection on Jones' legacy.
"George Jones' life is an example of so many wonderful things - how someone's God-given gifts can make this a richer, better place. How one human being can overcome adversity, addiction and life-threatening obstacles time and time again," Paisley wrote.
"That it is not the stumble or fall that counts, but the willingness to stand again. How a keen sense of humor and a twinkle in a person's eye can still prevail even after all of life's hard knocks. How mistakes, missteps, and bad choices are not the end of the world if a person chooses to turn them into something good. And George's life is above all the strongest example of how the love of a great woman can get a man through anything," the singer concluded. "All of this made its way beautifully into every note of the greatest voice country music will ever know, and one of the greatest friends you could ever have."
Paisley and Parton are just two of the several celebrities who shared their memories and respect for the singer/songwriter, who died in Nashville at 81.
Kris Kristofferson: "George Jones was the greatest country singer since Hank Williams and a truly beautiful human being. The world's a sadder place without him."
Alan Jackson: "Well, heaven better get ready for some great country music. While George was known for his wild and crazy days, I've known him for 25 years as a friend. He had grown into a real good man. Of course, he will always be the greatest singer and interpreter of real country music - there'll never be another. Like the song says, 'You know this old world is full of singers, but just a few are chosen to tear your heart out when they sing. Imagine life without them. Who's gonna fill their shoes.'"
Travis Tritt: "I am just devastated by the news that George Jones has passed away! The music world has lost one of the most original and innovative talents that the world has ever known. I feel such a personal loss of not only one of the greatest vocal influences of my life, but also I've lost a dear friend. Visits with George have always been full of joy and laughter. Every time I would see him, George would always greet me with a funny story or a joke! His legacy will put his name at the top of the most influential artists in history, right along with Hank Williams, Johnny Cash and Waylon Jennings. His voice will be influencing singers 100 years from now and beyond! I'm reminded of the lyrics that Waylon wrote in the tune "It's Alright". "If we all sang like we wanted to, we'd all sound like George Jones!"
Vince Gill: "There aren't words in our language to describe the depth of his greatness. I'll miss my kind and generous friend."
Loretta Lynn: "It's a sad day for country music and a great loss for those of us who knew him. I was blessed to call George my friend. He was one of the best country singers there ever was. My thoughts and prayers are with his wife, Nancy, and all of his family. It's a sad, sad day."
