The 24/7 digital rehearsal room for vocalists and musical ensembles.
Harmony Helper is a sophisticated vocal rehearsal platform that leverages digital signal processing (DSP) and optical character recognition (OCR) to bridge the gap between static sheet music and professional vocal performance. In the 2026 landscape, it stands as the industry standard for musical theater performers, choral groups, and vocal coaches. Its technical architecture centers on a proprietary 'Sheet Music Reader' that converts PDF or physical scores into MIDI-based polyphonic audio files. This allows users to isolate specific vocal parts, adjust tempo without pitch shifting, and practice against a synthetic but harmonically accurate background. The app's core value proposition is its real-time pitch-tracking algorithm, which provides visual feedback to singers on their accuracy relative to the score. For ensemble leads, the platform functions as a distribution hub, allowing directors to upload custom arrangements and track the practice metrics of their members. By automating the creation of practice tracks, it eliminates the need for manual piano recordings and significantly reduces the technical overhead of musical preparation for professional and educational groups.
