“When I write vocal melodies, it’s like phonetics,” Sheeran said. He said the phrase sounded like, “I’m thinking out loud”, which ultimately became the title.

On the stand, he sang the phrase “I’m singing out now”, which he said he sang during his songwriting session with Wadge. Sheeran testified for nearly an hour on Thursday, explaining how his friend and collaborator Amy Wadge started strumming the chords for the song during a visit to his home in England, and how they had collaborated on the lyrics. Townsend’s heirs are seeking a share of profits from Thinking Out Loud, saying that the syncopated chord progression was copied from Let’s Get It On.

The 32-year-old is being sued by heirs of songwriter Ed Townsend, Gaye’s co-writer on the 1973 song. “I draw inspiration from a lot from things in my life and family,” said Sheeran, saying the song was inspired by the love he observed between his grandparents.
