Impromptu Photo shoot Indianapolis 2018 Canal

Impromptu is an 8 member contemporary a cappella group based out of Indianapolis, Indiana. Founded in May of 2017, several members met at Ball State University or were good friends who wanted to come together, hang out and make music. Their unique sound is the result of a tight and soulful blend, some R&B and Jazz influences and a little sensuality.

Impromptu has had the opportunity of performing in the Varsity Vocals Open Midwest Semifinals two years in a row, taking home second place and best soloist in 2018. They also competed in Voicejam in Fayetteville, Arkansas, where they won 1st place, giving them the opportunity to travel to and perform in Taiwan for the 2018 Vocal Asia Festival.

Trevor Barnes (Baritone)

Trevor is a graduate of Ball State University with a Bachelor of Fine Arts in Graphic Design (18').  He became a part of the a cappella community during his undergrad by joining Ball State's all male a cappella group Note to Self. He joined Impromptu near the end of his college career, and is one of the in-house arrangers and social media managers for the group as well as a designer. Trevor is a Star Wars fanatic and a YouTube binge-watcher, as well as a lover of all types of potato and tortilla chips. He also loves being able to share his love of a cappella with a group of talented individuals and can't wait to perform for more audiences and share their sound with the world. 

Zach Yarborough (Bass)

A self-proclaimed renaissance man (jokingly), Zach holds degrees in music business and fine art, and has been an a cappella enthusiast for over 10 years. In his spare time, he also dabbles in writing, acting, and is currently hip-deep in a tattoo apprenticeship. Zach is looking forward to helping Impromptu bring their own specific brand of a cappella to the world.


Andrea Mellum (Soprano)

Andrea Greene is honored to sing soprano as 1/8th of Impromptu. She grew up in Columbus, Ohio fully immersed in music and theatre. She continued her studies at Ball State University where she stumbled into the world of contemporary a cappella. She quickly became the music director of Ball State’s first women’s a cappella group, Ladies Choice. During her time as music director Ladies Choice competed in the ICCA, advancing to Semi-Finals twice. She also served on the executive board for The Association of Collegiate A Cappella for two years, first as secretary and second as president. While her comfort in arranging lies with women’s groups, she is immensely enjoying the challenge of arranging for a very small mixed group! Singing with Impromptu is not only giving her a musical outlet post graduation, but is providing it at an extremely high level. Outside of impromptu you can find Andrea with her husband and their cat, probably drinking wine. She could not be happier singing with such a talented group of friends, and knows that the future of Impromptu is very bright.

Sam Doub (Alto)

Samantha Doub is a graduate of Ball State University and is currently living and working in Indianapolis. She is an alto 2 in Impromptu and also serves as one of the choreographers for the group. Some of Sam's hobbies include beatboxing and eating mac and cheese, as well as singing with her best friends, of course! She is very much looking forward to this summer and all of the fun things that Impromptu has in store!

Kaleem McGill (Tenor II)

Kaleem was born and raised in Indianapolis. He has always been involved in music, being a member of the Indianapolis Children’s Choir and Indianapolis Youth Chorale for years and singing in famous places such as The Lincoln Center in NYC, and to the National Grand Theatre in Beijing. He was very involved in music in high school, but took a break from music in college. He went to Indiana University and studied Communication and Culture. He now works for USA Today as an Account Relationship Manager in digital marketing. When he isn’t singing, he is obsessed with writing Yelp reviews and watching every cheesy horror film on Netflix. He’s so excited to have the chance to sing with these talented people, and can’t wait for the future of Impromptu.
