Jerrod Niemann and fiancee Morgan Petek will tie the knot in October, but they don't want wedding gifts.

The country singer and his soon-to-be wife will travel to San Juan, Puerto Rico to say "I do" next month, and instead of filling out their wedding registry at local chain stores, they're trying to help children in the name of music by asking for donations to Niemann's nonprofit, Free the Music USA.

"In lieu of a traditional wedding registry, we are asking for donations to be made to benefit Free the Music USA," the couple tells People.

Niemann's nonprofit organization strives to give instruments to children who may not be able to afford them otherwise. On its official page, the group states that all children deserve "the opportunity to explore music within themselves," which is why the singer created FTMUSA.

Charity is something the couple really supports -- in fact, it's always been a part of their relationship.

"Philanthropy has been a cornerstone of our relationship since the beginning," the singer and his lady tell People. "In the past, we have been blessed to team up with our friends at ACM Lifting Lives, Rising Star Outreach, PS22, Refugee and Immigrant Students Empowered and Songs for Sound to enrich the lives of young people. We can't think of a better way to honor our upcoming nuptials than to combine the two things that we love the most: music and helping others."

Clearly, Petek's love for helping others is one of the things that made Niemann fall in love with her. "It's so funny, the little things we can all get upset about," he says. "That's why it's just really cool to see somebody that really thinks of others and wants to make people happy."
