SETH BISEN-HERSH is a prolific and versatile New York City based musical theatre composer/lyricist and author who works as a pianist, accompanist, musical director, vocal coach and cabaret producer, and also dabbles in acting, singing, comedy and puzzle writing.

Bisen-Hersh grew up in East Brunswick, New Jersey where he started piano lessons at 8 and began composing songs at 13. He graduated from Massachusetts Institute of Technology with two Bachelors degrees (Computer Science and Music); then he completed his Masters in Music Technology at New York University. He began performing in shows in community theatre and summer theatre at a very young age, and was the musical director of EB’s award-winning Children’s Summer Theatre for many years. He directed many independent shows in EB, at MIT and NYU, creating many original revues of standard songs as well as his original ones.

Bisen-Hersh has completed the score (music/lyrics) for: Meaningless Sex, The Spickner Spin, More to Love , Stanley’s Party, Love Quirks, The Diamond as Big as the Ritz and Agatha Christie’s The Secret Adversary.

Meaningless Sex premiered at the 2003 New York International Fringe Festival where it won the coveted Audience Favorite Award out of two-hundred shows. The following year in 2004, The Spickner Spin also won the Fringe Festival’s Audience Favorite Award. More to Love which had a successful reading at Theater1010 in July 2009, was featured in the West Village Musical Theatre Festival in June 2014 where it won “Best Lyrics” in its series. Stanley’s Party is a children’s musical based on the popular books, “Stanley’s Wild Ride” and “Stanley’s Party” by Linda Bailey and had a critically acclaimed 6 week production at Manhattan Children Theatre in the Spring of 2010.

Love Quirks is a new musical based on actual events as a group of roommates explore the bizarre tribulations of love, friendship, and all the blurry lines in-between. It features some of Bisen-Hersh’s most popular cabaret songs, as well as new ones, and a poignant and hilarious book by Mark Childers. The show had a critically-acclaimed, audience-adored 3-week run in 2014 and a wonderful revised reading in 2015. In February 2020, Love Quirks started previews off-Broadway at the St. Luke’s Theater where it suspended performances 3 days before opening night. The production won 4 off-Broadway BroadwayWorld awards including Best Musical Production and Best Score. After 27th months, it triumphantly returned off-Broadway to the AMT Theater where it received rave reviews and ran for 12 weeks. It is now being licensed for productions around the world and had its college premiere at Hofstra University in April 2024. Its off-Broadway cast album is available streaming on all platforms.

The Diamond as Big as the Ritz has a book by R.C. Staab. Set to the rhythms of early 20th century music, F. Scott Fitzgerald’s comic novella is told through the eyes of young foreign woman seeking to immigrate to the U.S. With Fitzgerald’s deliberate satire involving impossibly wealthy Americans and the author’s cavalier treatment of race issues, the story takes on added comic satire and an edgy, engrossing perspective. The show had 2 successful NYC industry readings in 2017 and 2018 and its concept cast recording is available here. The anthemic finale: “Enough Already” was turned into a viral music video starring Mario Lopez and was a finalist in London’s prestigious 2019 Stiles & Drewe Best New Song Prize. In September 2024, the show had a 3-week run at the ATA Sargent Theatre.

According to his nephew when he was 5: “Uncle Seth is funny!”

And finally according to Stephen Mosher of BroadwayWorld.com: “A musical theater writer, Bisen-Hersh manages to create a clear story in each of his compositions, all of which are theatrical in nature and distinctly character-driven…Mr. Bisen-Hersh has found a voice that is more accessible to audiences than some more famous composers that get overly complicated with their lyrics by placing his focus solely on emotion, be it his, the character’s, the performer’s, or ours. As a poet, he has a knack for looking inside of the human heart and putting what he sees there on paper; indeed, the heart to be found in his work is most easily compared to the work of the late Carol Hall, while his storytelling skills are very reminiscent of the songwriting team of Maltby and Shire, not bad company to be in, in the opinion of this writer.”
