Duet Partner vs Harness

Duet Partner provides studio management tools for music teachers to schedule students, collect payments, report activities, and manage business operations. Its Season Smart Scheduler gathers families’ preferred lesson times and drafts a schedule based on teacher availability and priorities. The calendar handles recurring lessons, changes, cancellations, reminders, and attendance. Student records include profiles and sibling family groupings, with bulk email and text messaging and email templates. Duet sends studio-family information by text, with email as a backup; parents and students do not need Duet accounts. Teachers can collect credit card, Apple Pay, Google Pay, and ACH bank transfer payments through Stripe. Duet runs on Android, iOS, and the web. The monthly plan costs $9 a month, while the annual plan costs $99 a year; both include all features and charge a 1% transaction fee on family digital payments. There is no free plan, but a 30-day trial is available. The service currently supports access for a single teacher and does not provide a free studio website builder or an online studio and music-optimized video-conferencing platform.
