Ten men, 10 voices and one harmonized fusion of sound. They call themselves Hyannis Sound and they're a professional a cappella group out of Cape Cod that is making a huge splash on TikTok.

The group itself was founded back in 1994 by a young man named Townsend Belis, whose mission in life was to put together a perfect grouping of voices that when combined are nothing less than melodic. Through auditions, Belis was able to form Hyannis Sound, and the group recently celebrated its 25th anniversary.

Hyannis Sound performs its a cappella act throughout Massachusetts, singing an estimated 14-16 songs per show for all ages; "5-105," as they put it. Their diverse selection of genres is as eclectic as it gets to reach different audiences such as rock n' roll, theatre, music from the '40s, and pop, just to name a few styles.

With the pandemic taking over 2020, the group was unable to perform in front of a crowd so it took to social media and created a TikTok account. Fast forward a year later, and these gifted men are sitting on top of almost 800,000 followers with just about eight million likes. Not too shabby.

The group's TikTok got so much attention that after recording their own rendition of Alicia Keys' "Falling" that she reached out to Hyannis Sound and long story short, there's a collaboration on the way. From "Heartbreak Anniversary" by Giveon to "September" by Earth, Wind and Fire, these guys are well-rounded in their musical reach.

"We do live streams and have karaoke nights where people can actually donate any amount of money to us, and we sing a song that they request and it's really expanded our reach to audiences we didn't think would listen," said member Max Pinson. "We have people tuning in from Norway and the Philippines and all over the world. We have these fans that before 2020 referred to us as a "Cape Cod specialty," and it's great that we can continue to build a relationship with the Cape Cod community while also creating a broader audience."

Wonder how they choose their song selections? Everything is actually done in-house, right down to the song arrangement, which is mostly directed by Noah Berg, a prodigy within the group. Hyannis Sound writes its own parts rather than contracting them out to another music company. Seven songs are thrown into the ring and emailed out to the group to feel out each individual idea until finally a group decision is finalized. Their favorite current arrangement is their version of Gloria Gaynor's "I Will Survive."

The group is currently practicing in its studio on the Cape for the next couple of weeks and is already booking gigs well into 2022, all while changing the a cappella game one TikTok at a time.
