The Oscar-nominated composer, 70, exclusively tells PEOPLE about what the crowning ceremony was like, and how it was “heavenly” to hear his piece played in the historic venue.

“They all looked as if they were having a beautiful time. I’m sure they were immensely proud. Proud to be part of this historic occasion. They would smile and people would smile in the audience. I’m sure they recognized some of the Members of Parliament or some of the dignitaries,” Doyle tells PEOPLE of the family.

While the joyful “King Charles III Coronation March” was performedin rehearsals, “it wasn’t the same without the finery and the color and the real glamour and the theater of it,” the celebrated composer tells PEOPLE of the practice. “So to hear it played to its intended audience was a different experience completely.”

“I cannot emphasize how much the reverberation almost lifts the music into another sphere. There’s something about the reverberation in these large spaces and cathedrals that is heavenly. So it felt heavenly to hear my music played. The feeling of sheer joy,” Doyle tells PEOPLE of the epic experience and lifetime achievement.

“I didn’t actually shed tears till after that moment, because it was so exciting and overwhelming. In retrospect, it really sunk in how privileged I was to be part of this extraordinary day.”
