Giving competition to music apps like Smule, Harmony Helper said it plans to launch an app that gives singers a digital rehearsal room. The technology creates a learning tool that can do things like provide customizable sheet music scanning, vocal part mapping, real-time feedback, record/playback, vocal part volume control, group sharing, and more. It’s aimed at helping singers of all skill levels prepare for their time in the spotlight.
The app is expected to debut in the second quarter on iOS and Android.
“We are thrilled to debut Harmony Helper to the singing community,” said Andrew Goren, founder and CEO of Harmony Helper, in a statement. “As a musical theatre actor myself, I know the hassles of practicing for a performance can leave singers feeling frustrated and unprepared. My own experiences have inspired me to develop the solution that empowers singers with great rehearsals and helps them feel confident.”

Harmony Helper’s new sheet music scanner is unique. Users take a photo of any sheet music and upload it into the app, where it is presented in an easy-to-read format that allows custom isolation of their part.

This feature makes all music available to practice the moment a singer is ready to begin learning. For singers who are just learning or struggle with reading sheet music, this patented technology eliminates the friction to allow the aspiring singer to practice.
The Mount Laurel, New Jersey-based company said performers no longer have to line up an accompanist to play and record music, and the real-time feedback feature takes away the stress of scheduling with a coach to quickly prepare for an audition or performance.
For all singers, the Harmony Helper app is a rehearsal tool that puts control of rehearsal time and location in the hands of the performer. Using patented layered recording technology, singers can practice and record a part of a song, get real-time feedback, and make adjustments accordingly.
“Learning to sing requires only one really big commitment: practice. Harmony Helper allows you to practice anytime, while simultaneously training both your brain and ear with crash courses that are sure to have anyone harmonizing in no time,” said Rob McClure, Tony-nominated actor and artistic adviser at Harmony Helper, in a statement. “Unlike other apps on the market, Harmony Helper makes it possible for singers to practice any song they want with no song library limit. The sheet music scanner feature puts control back into the singer’s hand, without having to rely on the director or a friend to record their parts. As a Broadway performer, this is incredibly valuable and a first for the industry.”
Another Harmony Helper feature is vocal part mapping, where a singer can isolate a part of a song for a custom-tailored rehearsal. The app can accurately visualize the singer’s pitch and timing, calibrated to their abilities and level of expertise, and provide real-time feedback. Such features appeal to music and choral directors, voice coaches, and teachers.

Being able to easily share arrangements with their singers frees instructors from innumerable one-on-one coaching sessions, allowing them to focus on improving the performance of the group. Performers receive their music via the app and are able to easily isolate their part so they can practice on their own time, not just when the director or accompanist is available.
Vocal coaches and training experts can encourage their students to practice with the Harmony Helper app at home, so they can make further progress during their session time. Harmony Helper is also a cost-effective learning tool for those who cannot afford a vocal coach or rehearsal space, allowing them to enhance their skills and performance.
“Harmony Helper is like having a rehearsal studio in the palm of your hand,” said Amy Shoremount-Obra, soprano at the Metropolitan Opera, in a statement.
The app has a 14-day free trial (unlimited songs). For a monthly subscription (unlimited songs), it costs $8. For an annual subscription (unlimited songs), it costs $76. It also has group pricing. Harmony Helper has 30 employees. Competitors include Yousician, Appcompanist, Smule, and TikTok.
